Description

Technical Field

[0001] The present invention relates to a two-dimensional material with an endogenously extensible electronic cloud flat band and a preparation method thereof, belonging to the technical field of two-dimensional materials. Background Art

[0002] The flat band of crystal materials. In the academic community, a special energy band with a flat energy distribution in the electronic energy band structure found in crystals is called a flat band (FB). In the flat band, the energy of electrons does not change with the change of momentum, which means that the effective mass of these electrons in this energy band approaches infinity, thus showing localization characteristics.

[0003] The localization characteristics of electrons in the flat band make them insensitive to external perturbations, so that a quantum confinement effect or a compact localized state (CLS) can be formed. CLS is a special quantum state in which electrons are confined to several adjacent lattice points, forming a highly localized wave function.

[0004] The currently studied flat band and its CLS state are only for establishing a mathematical theoretical model, and the scope is limited to between several atoms of the lattice, with a radius within 1 nanometer, far from reaching the macroscopic quantum state (between micrometers and millimeters).

[0005] Two-dimensional materials. Two-dimensional materials are a new type of materials with a thickness ranging from a single atomic layer to several atomic layers. The most typical representative of two-dimensional materials is graphene, and monolayer graphene has only one atomic thickness, about 0.34 nm (3.4×10 -10 m or ). Two-dimensional materials have strange properties different from ordinary materials, which originate from the quantum confinement effect caused by their ultra-thin thickness. For example, the massless Dirac electrons near the K point (Dirac cone point) in graphene have extremely high carrier mobility; monolayer WS2 is a direct bandgap semiconductor with an extremely large exciton binding energy and valley spin optical properties; monolayer TaS2 has superconductivity; monolayer NbTe2 shows metallicity; few-layer Bi2Se3 is a topological insulator; monolayer BN is an insulator, etc. These strange properties make two-dimensional materials a research hotspot in physics, chemistry, and materials science, and are expected to solve the short-channel effect faced by conventional semiconductors, enabling further reduction of the transistor size. [1] .

[0006] Currently, the scale of two-dimensional materials developed by people is still very small. The sizes of the above-mentioned two-dimensional materials at the laboratory level are mostly between nanometers and micrometers. Except for single-layer graphene, the rest of the two-dimensional materials are far from having the technical conditions for industrial production. Most of the molecular structures of the materials are mainly composed of weak ionic bonds to covalent bonds between metal and non-metal elements, and the macroscopic mechanical properties are brittle and lack ductility. The crystal structure tends to be a nano-sized tiny molecular crystal. The flat band effect that may occur within the molecule and the range of its compact localized states are extremely small and uneven, and are all restricted within the molecule.

[0007] Metallene. Metallene is an atomic thin film material composed of metal atoms with deficient coordination, and has become a new category of two-dimensional materials.

[0008] As a new member of two-dimensional materials, many metallenes with different structures have been reported, such as Figure 1 listed, the layered metallenes include elemental antimony Sb( Figure 1 a, double-folded state α, single-folded state β), bismuth Bi( Figure 1 b, washboard state α, double-folded state β), and the non-layered metallenes include elemental germanium Ge, gold Au, hafnium Hf, tin Sn, and the intermetallic compounds palladium-zinc planar molecule Pd5Zn2, palladium-cadmium planar molecule Pd5Cd2, etc.( Figure 1 c, d, e, f, g, h). These metallenes exhibit excellent physical and chemical properties, including catalysis, plasmonics, photoluminescence, and magnetism, etc., and these properties are particularly beneficial for biomedical applications. [2] 。

[0009] Among several spatial structures of metallene, the folded state cannot produce a uniform flat band. And for planar molecules, due to the deficient coordination state of internal atoms, even if there is a flat band structure, it is defective, just like there are vortices on a horizontal plane, resulting in the flat band presenting an uneven and discontinuous state. In addition, since the research on metallene focuses on the generation technology and effects of the unsaturated coordination between atoms, that is, the deficient coordination state of atoms in the crystal, and tries to find exotic quantum states in defects, it does not pursue the internal flat band structure of the molecule itself.

[0010] Electron-phonon coupling mechanism. For the development and control of material magnetism, superconductivity, and other quantum effects, the "electron-phonon coupling mechanism (abbreviated as electron-phonon coupling, i.e., Cooper pair mechanism)" is a core control element and plays a fundamental decisive role, where the stability and controllability of the coupled state are crucial. However, since its coupling effect is at the level of the atomic lattice structure and even the subatomic structure of the coordination of smaller-sized ion cores, the truly significant factors lie in the interactions between multiple atoms, ion cores, and even atomic nuclei. For this logical picture of the outward-inward correlated interactions, with each step across a hierarchical level, the correlated factors multiply, making the state of the interaction field between the centroid distances of atoms extremely complex and strange, including coordination number and coordination field, bond energy and bond length, energy band and energy gap, charge density wave, electron spin density wave, spin-orbit coupling, spin magnetic moment, Coulomb repulsion effect... and so on, many factors that are both correlated and distinct or even contradictory. When existing mathematical models are used for description and calculation, these factors cannot be unified into a single function system, often missing the mark here while losing something there, showing a chaotic state structure; macroscopic solid materials, as many-body systems of a super-large number of atoms, the "electron-phonon coupling effect" masked by the lattice shows quantum physical effects in the macroscopic world. The macroscopic means such as pressure, light, electricity, magnetism, sound waves, and thermal fields applied by humans from outside the system are often too large in scale and too low in intensity to be effective, having little impact on the combined state between individual atoms. When atoms form crystals and lattices, they basically show a disordered layer structure. And the electron motion based on the lattice structure and its coupling with various factors are based on the spin and orbital motion of atomic nuclei and electrons, as well as the condensed state generated based on these spins and orbits. From the perspective of symmetry principles, it is difficult for a disordered layer structure to naturally form a long-range order that produces quantum strange effects macroscopically. Up to now, the theoretical issues of the electron-phonon coupling mechanism have not been completely resolved.

[0011] Superconductivity. For the mechanism of low-temperature superconductivity, the BCS mechanism proposed by Bardeen, Cooper, and Schrieffer, namely the "Cooper pair" mechanism and equations, relatively rigorously solved the theoretical problem of the formation of conventional superconductors with a superconducting critical temperature Tc near 0K. Its basis lies in Bose-Einstein condensation (BEC), a type of quantum phase transition (a second-order phase transition, which is a phase transition where all atoms in a potential well condense into the ground state, that is, atoms that were once hot and completely disordered all become completely ordered and described by the same wave function in quantum mechanics), thus establishing a "long-range order" and presenting the "novel macroscopic state" of superconductivity. This is the state that occurs when atoms are cooled to the order of a few K or even a few micro-K. That is, electrons are transformed from fermions into bosons due to "pairing", namely "Cooper pairs", and "lose magnetism externally", resulting in the lattice electromagnetic field "fence" of atoms or ion cores suddenly losing its influence on "Cooper pair electrons". "Cooper pair electrons" move freely and unobstructedly in the lattice of the material like ideal gas molecules, such as N2, O2, etc. in a thin space. In particular, after Cooper pairs form a directional current in an electric field and the electric field is removed, the Cooper pair electrons still do not stop flowing and can form an automatic and eternal current in a circular circuit, becoming a permanent magnet and being able to levitate in a magnetic field. The formation of Cooper pairs macroscopically manifests as the sudden disappearance of the material's resistance and the overflow of the magnetic field (no magnetism inside the material), so the material exhibits superconductivity and complete diamagnetism.

[0012] However, the BCS mechanism cannot explain the "high-temperature superconductivity" phenomenon and high-temperature superconductors, such as a series of cuprate superconductors, iron-based superconductors, and organic superconductors, discovered since 1986. That is, superconductors with a relatively high superconducting phase transition critical temperature Tc. The Tc of these superconductors has exceeded the McMillan limit of below 40K predicted by the BCS mechanism. There are even ceramic superconducting materials with Tc reaching above 100K, such as mercury barium calcium copper oxide HgBa2Ca2Cu3O 8+δ Superconductor, with Tc reaching 133K under normal pressure (it can be further increased to 164K under pressure). Because at this "high temperature", it is obviously impossible to occur Bose-Einstein condensation (BEC) in the traditional sense. Some people refer to the superconductivity of single-element materials (low-temperature superconductivity) as s-wave superconductivity from a phenomenological perspective, and the existing high-temperature superconductivity as p-wave superconductivity, that is, superconducting mechanisms relying on the outer s-electron orbit and p-electron orbit of atoms respectively; in addition, there are also many discussions about d-wave superconductivity, such as "d-Wave Superconductors" written by Xiang Tao, an academician of the Chinese Academy of Sciences.

[0013] Since the theoretical problems of the electroacoustic coupling mechanism have not been fundamentally solved, practice and experiments have shown extremely rich diversity and uncertainty. Neither the theoretical community nor the industry has formed a unified understanding. On the one hand, this has led to the fact that superconducting materials at "high temperature" or room temperature (15-30°C environment under 1 atmosphere) above the freezing point (0°C, or 273.15K) have not yet appeared (never discovered or developed by humans). On the other hand, there may be new molecular structures that can be simplified or simply solved, which can eliminate or suppress many interference factors in the electroacoustic coupling through spontaneous and orderly interactions between the atoms that make up the molecules, and highlight the coupling factors, so that the so-called "electron-phonon coupling" can achieve strong correlation and stability at room temperature and above.

[0014] From the analysis of the atomic structure of the copper oxide superconductor lattice, the copper and oxygen atoms can form a so-called "copper layer", that is, a region with a high density or a large number of electrons as carriers, which prepares paired "raw material electrons" and a microenvironment for the adjacent layer to become a superconducting layer, that is, the Cooper pair field, which intuitively seems to form a necessary condition for superconductivity. However, the "copper layer" alone is obviously far from enough, and, from the actual analysis, the "copper layer" is not even a necessary condition for superconductivity. For example, the metals with the best conductivity among single metals are silver Ag, copper Cu, and gold Au. Their lattice structures are all face-centered cubic, the most compact type, and the coordination number is saturated 12. Similar to the lattice structure of most metals, the stronger the conductivity, the more free electrons are contained in their lattices on average, which is intuitively a "natural storage layer". However, gold, silver, and copper are not superconducting materials, while zinc Zn, cadmium Cd, and mercury Hg, which are adjacent to them in the same period, have very low conductivity at room temperature and cannot be regarded as having a good "storage layer", but they can all become superconducting materials at low temperatures. It can be seen that superconductivity and electronic states under the control of quantum physics laws do not follow the classical laws of conductivity. The more carriers there are, the better or stronger the superconductivity is. Electronic "Cooper pairs" are the real physical basis of superconductivity.

[0015] High pressure is another condition for achieving superconductivity. Semiconductors Ge and Si can be metallized under high pressure and enter a superconducting state, with superconducting phase transition temperatures of 6.7K and 5.3K, respectively. Similarly, by applying pressure, non-metallic elements or metal elements of the main group such as phosphorus P, arsenic As, antimony Sb, bismuth Bi, oxygen O, sulfur S, selenium Se, tellurium Te, bromine Br, and iodine I, together with iron Fe, active metal elements such as cesium Cs, calcium Ca, strontium Sr, barium Ba, scandium Sc, and yttrium Y, can all become superconducting materials. In particular, a German experimental group found that hydrogen sulfide H2S can be superconducted at 200GPa (2×10 11 Pa, that is, 2 million atmospheres, close to the pressure at the center of the earth ~3×10 11 Superconductivity at 190K appears under high pressure of 1.3 Pa[3] High pressure can be regarded as the phonon energy level elevation effect inside the atomic lattice. However, it is very difficult to achieve and maintain too high pressure in industrial technology. Even if it can be achieved, safety cannot be guaranteed, and it basically has no practical value.

[0016] In recent years, a series of new unconventional superconductors have been discovered in natural and synthetic materials, including organic superconductors, iron-based superconductors, magic-angle graphene superconductors, gated semiconductor superconductors, surface and interface superconductors, etc. On May 23, 2024, Qijin Chen from the University of Science and Technology of China / Hefei National Laboratory, Zhiqiang Wang, Shuolong Yang, K. Levin from the University of Chicago in the United States, and Rufus Boyack from Dartmouth College, etc., were invited to publish a long review article in the latest issue of Reviews of Modern Physics, titled "When superconductivity crosses over: from BCS to BE C". The article systematically analyzed and commented on these new experimental findings, pointed out that they belong to the BCS-BEC crossover type superconductivity, the electron pairing strength is in the intermediate transition region between the two extreme ends of BCS and BEC, showing obvious pseudogap phenomena, and gave relevant experimental criteria. This theoretical innovation is still based on the "Cooper pair", but it has developed from the original simple BCS mechanism to the entire interval from BCS to BEC.

[0017] However, the underlying logic followed by the electron-phonon coupling state of the Cooper pair is still unclear - the superconducting critical temperature Tc cannot exceed the boiling water temperature of 100 °C (373 K), or even reach 0 °C (273 K), indicating that people's research on condensed matter physics and the control ability of the stable and ordered state of quantum microstructures are still at a relatively low level. Superconductivity with an expected Tc around 100 °C can be called "water temperature superconductivity".

[0018] As can be seen from the above analysis of the technical background, for new electromagnetic materials, existing two-dimensional materials, superconducting materials, etc. that are macroscopic quantum functional materials, the main problems in their research and development and manufacturing are as follows: ① The theoretical issues of unconventional superconducting mechanisms such as high temperature or room temperature remain unresolved; ② Room temperature superconducting or "water temperature superconducting" materials are urgently needed to be developed; ③ There is a lack of research on linking the electron-phonon coupling mechanism with the electronic flat band structure; ④ There is a lack of ideas and methods for linking superconductivity with the endogenous electron cloud flat band in crystal materials; ⑤ There is a lack of an effective molecular architecture model for the endogenous extensible electron cloud flat band structure in crystal materials, especially a lack of an architecture and model that combines the electron cloud flat band structure with two-dimensional molecules and two-dimensional molecular materials; ⑥ There is a lack of technical means for large-area expansion of the electron cloud flat band beyond the nanoscale; ⑦ The problem of effectively controlling the electron motion and its field form (wave function / cloud structure) in materials remains far from being solved.

[0019] In summary, at present, due to the limitations of their molecular structures, two-dimensional materials have problems such as small size, high manufacturing cost, and difficulty in developing industrial production process technologies. Summary of the Invention

[0050] The core principle of the molecular structure of the present invention is: a two - dimensional layered symmetric multi - atom layer molecular structure of bimetallic elements based on making up for the spin symmetry breaking of transition element atoms M and creating a new symmetry of the condensed matter system as the structural stability basis. This molecular structure can automatically achieve the sandwich extraction and aggregation of the electron cloud towards the M atom layer of the two - dimensional state molecular symmetry plane, and its aggregation state can be automatically regulated with the change of environmental temperature and pressure, thus presenting an overall characteristic of the molecular structure, achieving a new symmetric state of atoms. This molecular structure is called the "alkene - type alloy molecular structure with symmetric sandwich - layer extracted electron cloud". The typical characteristic of this structure is that the central layer inside the molecule has a complete endogenously extended flat electron cloud band, the cloud density of this electron cloud band is greater than the density of other parts of the molecule, and it evolves into the delocalized orbit of all the ion cores in the molecule, and then becomes the orbit of the whole molecule, and quantum tunneling effects can occur at the molecular edge

[0051] The theoretical analysis is as follows

[0052] From the specific practice of unconventional superconductivity, the elements that are currently recognized by the scientific and technological community and may achieve the unconventional high - temperature superconducting state generally include: ① ultra - high pressure PS , i.e., the pressure value close to the earth's core is 10 11 Pa to 10 12 Pa, or 10 6 to 10 7 atm; ② is the ultra-large specific surface area F required for the average free path of electronic long waves S , and the only morphology that can satisfy a macroscopically "infinite" specific surface area is an ultra-thin surface, i.e., a two-dimensional material; ③ is a sufficient condition for the delocalized orbital of molecules: the wavelength L of the molecular coherent wave (CW) cw is large enough, at least above the micron level (>1 μm), i.e., in the terahertz (THz) wave band of 10 12 to 10 14 Hz. The alkene-type alloy molecular structure of the symmetric sandwich layer of the two-dimensional material provided by this application can achieve the same or even better effect as the external ultra-high pressure through the sandwich aggregation of the electron cloud without the need for external pressure.

[0053] The optical tweezer technology described in this application is a laser control technology invented and improved by Arthur Ashkin et al. in the 1970s and 1980s. This technology uses a laser beam injected into a vacuum chamber to trap a single atom in a vacuum and keep the atom stationary. The optical tweezer is also called a single-beam gradient force optical trap. The optical tweezer for trapping micro-particles is a special optical field. When this optical field interacts with a small object, the object is affected by the light as a whole and thus achieves the effect of being "clamped". Then, the object can be moved by moving the light beam. If a region with a radius of a few microns is defined with the center of the optical field as the center, it will be observed that once a small object enters this region, it will automatically and quickly fall to the center of the optical field, showing that this optical field has an effect of centripetal gravity, or an optical trap effect. This special optical field creates a region with a lower potential energy (similar to the bottom of a bowl), that is, there is a potential barrier (similar to the wall of the bowl) from inside this region to outside. When the kinetic energy of the object is not enough to overcome the potential barrier, the particle will always stay in the trap. Although the process of the interaction between light and the object is invisible and intangible, the result shows that the object affected by the optical tweezer is moving along a specific route. The situation of the optical tweezer transporting particles is very similar to an invisible manipulator, and this invisible manipulator can freely control the target particle according to the operator's will.

[0054] The technology of atomic laser cooling associated with optical tweezer technology. Its principle is that atoms can absorb resonant light. If resonant light is irradiated against the motion of atoms from six directions, their kinetic energy can be taken away very quickly, thereby reducing their temperature from room temperature to the order of millikelvin (mK) or even microkelvin (μK). This technology has now been widely applied in practice, and any cold atom laboratory is equipped with an atomic laser cooling device. Since laser aggregation can form an optical trap, tiny objects are trapped at the optical trap by the optical pressure. Moving the light beam makes the tiny objects move with the optical trap, and thus displacement or surgical operations can be performed on tiny objects (ranging from single atoms to as large as viruses, bacteria, and intracellular organelles and cell components, etc.) under a microscope.

[0055] Research and progress on high-precision atomic clocks [4] , which has led to the great development of quantum entanglement and ultra-strong and ultra-fast laser technology. Because optical atomic clocks require the application of ultra-cold technology and laser superlattices, the current accuracy of atomic clocks has reached 10 -20 seconds. Correspondingly, in order to reduce background noise, first, it is necessary to keep the atoms stationary and overcome the so-called time dilation effect; second, a large number of atoms need to be gathered together. Scientists have been able to assemble more than one million atoms in an artificial crystal formed by two interfering laser beams (if the crystal is cubic, the length of each side exceeds 100 atoms. For example, using strontium Sr atoms, that is, the side length exceeds 43 nm). By using an optical tweezer as a magneto-optical trap to manipulate single atoms, the assembly of atoms can be achieved, and the atoms assembled in the optical lattice will naturally undergo quantum entanglement and generate coherent waves. The research on the quantum entanglement of many-body systems is considered by the academic community to be the second quantum revolution.

[0056] This application provides a new perspective for observing and examining quantum effects represented by superconductivity. From the macroscopic physical state of superconducting materials, mapping the Cooper pair electrons that are the microscopic material basis, the entire field where Cooper pairs move can be regarded as a new orbital of a whole macromolecule, that is, a delocalized orbital between multiple atomic group settlements (or clusters) that make up the solid. This delocalized orbital integrates the redundant electron cloud structures or redundant states (opposed to degenerate states, redundant states can be regarded as the wave function miscellaneous states in the symmetry-breaking space caused by the disordered layer structure of atomic packing) scattered throughout the lattice (between each lattice point), enabling the atoms and their condensed state structures to achieve higher symmetry externally (magnetic field energy can overflow, internal energy structurally degrades, constituting a supermolecule state with macroscopic dimensions in terms of electromagnetic properties), thus becoming a new all-region state structure. This new structure has quantum effects on the macroscopic scale and can satisfy the orbital symmetry of atoms and the translational symmetry (time translation, space translation) of the condensed state macroscopically, and has the conservation of energy, momentum, and angular momentum. These conserved quantities can be regarded as a compensation mechanism for the broken symmetry of the atomic condensed state. The electrons running in the macromolecular orbit, except that the activity field extends beyond a single atom and atomic cluster and then reaches the entire space occupied by the "object", have the same physical state as the electrons in the normal atomic orbit: they all follow the principle of the lowest energy, Pauli exclusion principle, and Hund's rule.

[0057] Due to following the principle of the lowest energy, the electrons in the molecular delocalized orbit are inherently inclined to enter the orbit in the form of "pairs with opposite spin directions". This pairing is ultimately just the natural extension when atomic orbits combine to form molecular orbits. If all the ion cores in an alloy are regarded as a single atomic nucleus, then the entire material is like a super-large atom, and the delocalized molecular orbit is equivalent to the outermost orbit of the super-large atom. The electrons first pair up in a spin-inverted manner and then move in the delocalized orbit. However, this electron pairing no longer depends on the parity of the element serial number or the dispersion of the outermost electron sublayer, but on whether the number of atoms forming the material state reaches the limit value. When the number of atoms is large enough to exceed the limit, regardless of whether the number of outermost free electrons is odd or even, since they are all discrete with respect to the ion core, that is, they are all relatively free, they can freely form Cooper pairs. Even if there is one unpaired electron, it will have no significant impact on the massive atomic communities (containing more than a million atoms).

[0058] The problem is only that the temperature for forming the macromolecular delocalized orbit (theoretically equal to the critical temperature of the superconducting phase transition, that is, Tc) is too low. Currently, the highest Tc value in superconducting materials has not exceeded 200K. Guided by the formation of the "delocalized molecular orbit", this application proposes the basic configuration of "alkene-type alloy molecules that extract electron clouds with symmetric sandwich layers", and has three purposes and functions:

[0059] One is to form a symmetric film structure among metal atom clusters, which facilitates the movement of the electron cloud in a "super-large degenerate space" with a long-range macroscopic two-dimensional state and microscopic three-dimensional state (at the picometer scale of 10 -12 m compared with the angstrom scale of atoms at 10 -10 m and the nanometer scale of atomic clusters at 10 -9 m), with extremely small interference in the vertical direction and good element synchrony. This liberates free electrons and their electron clouds from the strong interference of the disordered layer structure of ordinary metal-state microcrystals formed naturally or artificially. Furthermore, taking the size of atoms and atomic layers as landmarks, a standard framework for the operating ranges of ion cores and delocalized electrons and their cloud structures is built. This standard framework is a spatial geometric framework, sharing the same underlying logic as the electron wave function of atoms and its spatial extension structure, that is, the relationship formed by the spin, orbiting, and electromagnetic interactions between the atomic nucleus and the extranuclear electrons. Electrons, in the form of a Fermi cloud (wave function), operate in this framework. For example, a continuous stream of people walks through a super-large corridor that is about 200 meters wide and high and infinitely long. The environment is free and spacious without the intrusion of natural disasters such as wind, rain, thunder, and lightning.

[0060] The second is to achieve the central aggregation tendency or trend of the electron cloud. That is, taking the transition metal atom M with a relatively small radius and relatively large electronegativity as the symmetric center layer, and the active metal atom A with a relatively large radius and relatively small electronegativity as the two wings of the charge storage layer. With the gravitational difference of free electrons as the leading factor, a gravitational / pressure integration effect is formed from the surrounding to the center and from the two wings to the middle layer. This effect can make the space in the middle atomic layer (with a thickness of the real-time diameter D M ) of the M atom or the space between two M atomic layers (with a thickness of the distance d M-M ) between the atomic nuclei of two M atoms reach the maximum electron cloud density, thus creating the highest pressure, the strongest electromagnetic effect, or the most powerful anti-interference shielding ability, squeezing out novel quantum phenomena or quantum states that are difficult to present under natural conditions, that is, forming an endogenous electron cloud flat band and evolving into a delocalized molecular orbital. On the one hand, the ability of M atoms to contract and attract electrons in the A lattice field is limited. On the other hand, the A ion core has a relatively large volume and a relatively high compressive "hardness", and is limited by the chain traction effect caused by the M atomic layer's attraction of electrons. The internal contraction force and anti-contraction force of the system immediately reach equilibrium, and the framework stabilizes. However, the pressure value integrated into the central M atom may become extremely large, far exceeding the so-called ultra-high pressure artificially applied from outside the system. Also, because this effect is caused by the effective integration of the electromagnetic interactions between atoms, its ultra-high pressure effect is also contained in the density and degenerate state changes of the electron cloud in the M central layer, and in the endogenous electron cloud flat band, that is, the ultra-high pressure has the properties of endogeneity and self-equilibrium and does not require external pressure. Therefore, this structure may completely solve the current "superconducting high-pressure" problem.

[0061] Thirdly, it is to avoid the transfer of electron gain and loss in chemical molecules formed by chemical reactions between metals and non-metals, that is, the electron orbital jump to form positive and negative ions, which in turn leads to the result with the electrostatic attraction between positive and negative ions as the basic structural element. The boundary and chemical bond between positive and negative ions have strict directionality, which is a simple and rigid state for electrons and their cloud motion (cloud computing), completely losing flexibility. The outermost free electrons that should represent the most active state in atoms are restricted in a potential well constructed by an ionic electric field, not only blocking all possible novel quantum phenomena, but also the resulting material is brittle and has no macroscopic ductility. Due to extremely poor plasticity, it is not conducive to industrial manufacturing, and its application scenarios will be greatly limited. However, in the alloyed bonding state between transition metals and active metals, there are only the approaching (e→M * ) and departing (A * →e) states of the outer electrons to the two ion cores. The electron displacement is regulated by the different and constrained semi-free states of "A / M atomic nucleus / ion core", and the behavior of electron gain and loss will not occur. The non-jumping displacement of electrons between two different types of atomic nuclei or ion cores can drive the approach and merger of the outermost orbits of the two atoms. Its directionality will be weakened. With a large number of atoms pushing and squeezing in an "ordered layer" behavior, the ultimate trend is to merge the two outermost orbits into an ultra-large ring-shaped wave function (imagined and analogized to the ring of Saturn) that wraps all ion cores, thus forming a delocalized macromolecular orbital, which in turn becomes the basis for novel quantum states, such as forming a macromolecular magnetic moment, achieving superconductivity at room temperature and even above the boiling water temperature, becoming a new type of nano-chip memory, and can be used as a precursor or component of an ultra-micro and ultra-sensitive detector, etc.; at the same time, the microscopic structure of this alkene molecule is the same as the atomic coordination structure of the metal alloy, and it has good ductility and plasticity on the macroscopic scale, which is convenient for industrial manufacturing and processing.

[0062] The present application provides a method for preparing a two-dimensional material of an alkene-based alloy molecule with a symmetric sandwich-layer extracted electron cloud as the basic structural unit. By means of laser cooling, optical tweezer driving control, and artificial magneto-optical potential well-laser superlattice technology, the assembly of atoms, clusters, molecular and cellular structures, etc. is carried out to create new physical states, which is a major progress in the field of cold atoms. For multi-body entangled states, the background noise of individual particles can be greatly reduced or shielded, thus improving the measurement accuracy. On the other hand, with the expansion of the laser superlattice volume, the number of atom assemblies extends from the microscopic scale to the macroscopic scale. A series of quantum characteristics will be correlated with classical physical properties through chaotic effects-self-organized criticality, becoming a source for the development of novel physics. This is a law of universal significance demonstrated by cross-scale interactions, that is, a classical phenomenon of a macroscopic state will naturally emerge from the collection of a large number of quantum states under a certain background (More is different - Anderson). It can be verified through trial production whether it has superconducting, exotic magnetic or other novel quantum physical effects.

[0063] Based on the first principle of manufacturing new substances through atom assembly, the present application makes full use of existing high-tech means and provides a new method for manufacturing novel molecules by means of ultracold laser atom assembly, filling the gap in current industrial production technology. From the perspective of material and component manufacturing, there is still a fundamental problem in the existing industrial technology for alloy production, that is, for atomic sizes, the "meter"-level operating length in industrial production is hundreds of billions to trillions of times the atomic reaction (separation or combination) size. Therefore, the existing industrial production technology "cannot control" the long-range ordered arrangement of individual atoms, resulting in a disordered layer structure in which the three-dimensional macroscopic state after alloy solidification is always stacked with basic structural units of grains with an average size of about 100 micrometers (0.1 mm). To solve the problem of material ordering, fundamentally speaking, it is necessary to take the atomic scale (10 -10 m) as the standard, and it is required to start controlling from structures and scales below the nanometer and even picometer (10 -12 m) levels in order to develop new macroscopic structures and physical states based on ordered structures of atoms, clusters, molecules, etc.

[0064] The most remarkable feature of the novel alloyed alkene molecule proposed in the present application is that through the planar atomic combination of the sandwich layer, an effect can be generated in which the atomic lattice spontaneously aggregates a greater electron cloud density on the middle symmetric plane, and as the molecular weight increases, this effect forms an electron cloud flat band and then evolves into a molecular delocalized orbital. That is, this is essentially due to the action of electrostatic attraction (electronegativity difference Δe MA = e M - e A) The resulting aggregation is very likely to "give rise to" novel quantum phenomena as the plane gradually expands towards "infinity", providing at least a new structural form for condensed matter, and thus potentially changing the state where the critical temperature of current copper oxide-based superconductors cannot exceed 200 K. If alkenyl molecules with symmetric sandwich layers that extract electron cloud flat bands and have melting points above 300 K or 400 K can exist stably, they themselves constitute direct evidence of a series of quantum effects.

[0065] This negative charge aggregation effect, due to the stable structure of "same atoms in the same layer, different atoms in adjacent layers, and symmetry on both sides", provides an almost infinite boundary for the movement of the electron cloud within the space formed between two sandwich-symmetric layers of A atoms [odd-layer symmetry, i.e., (A…AMA…A) N type molecules] or between two layers of M atoms [even-layer symmetry, i.e., (A…AMMA…A) N type molecules] - that is, the migration freedom of the electron cloud from the original space composed of one atom or several atoms (cluster molecules, microcrystals, etc.) is expanded. Through the creation of the flat band bridge of atoms structure, it lays the foundation for the spontaneous formation of new energy levels of the flat band of electrons within the molecule. This will increase the activity range and pressure of electrons, change, collectively transfer, or even eliminate the Fermi energy gap in a small atomic framework, and establish a controllable framework for communication between quantum physics and macroscopic state physics.

[0066] From the speculated size of the electron itself (radius ≤ 10 -22 m) and the comparison of its energy level intensity, it is the smallest and strongest elementary particle that humans can currently recognize in the universe. The spatial distance between atomic nuclei in condensed matter on Earth (10 - 10 m, that is, the distance between atomic nuclei or the average equivalent diameter of atoms) is trillions of times (10 12 ) larger than the diameter of the electron. This is about 10 times larger than the ratio of the distance between the Sun and the Earth (1.5×10 11 m) to a person's height. Thus, it can be seen that the spatial movement of electrons around atoms has a great deal of intuitive freedom. However, this freedom is extremely collapsed or degenerate due to the strong binding force between atomic nuclei and electrons. The collapse is manifested as the combination of four quantum numbers, namely: the main layer (principal quantum number n), the sublayer (azimuthal quantum number l), the orbital angular momentum (magnetic quantum number m), and the spin state (spin quantum number m s ). The four quantum numbers constitute the wave function of the electron, determining the energy level and motion phase of each electron. The actual movement freedom of the electron can only be within the domain determined by its wave function. The overall wave function of the extranuclear electrons of an atom or an element determines the energy level structure of the atom or element, which is the fundamental determinant of its physical and chemical properties.

[0067] Although the electric field gravitational force of the atomic nucleus on electrons is very strong and can effectively bind the extranuclear electrons in the normal state, it is insignificant compared to the magnetic repulsive force between the two: Only the central pressure field of a star the size of the sun can cause nuclear fusion reactions (hydrogen nuclear reactions, that is, protons and neutrons fuse into helium nuclei), but it cannot make protons capture electrons to become neutrons. Only in the formation process of neutron stars does the reaction of protons capturing electrons to form neutrons occur, but electrons do not disappear or disintegrate in neutron stars because there is an extremely strong magnetic field around the surface of neutron stars, and its intensity can even split a single photon, indicating that neutron stars are like a huge superconductor - the magnetic field overflows and the surface current surges; Only black holes, the most powerful gravitational celestial bodies in the universe, seem to be able to fuse electrons, quarks, photons and other energy quanta together to become an undifferentiated extreme supermassive dark field. Compared with neutron stars and black holes, the energy exchange levels of chemical reactions, electrostatic attractions and other atomic separations and changes in the wave functions of extranuclear electrons on Earth can almost be treated as zero. However, in human activities on Earth, the energy levels of chemical reactions are significant and intense, constituting the basic driving force for biological life activities.

[0068] From the structural relationship between the atomic nucleus and electrons, the atomic structure can actually be metaphorically described as a membrane vesicle state. A drop of water can form many membrane vesicles, and the molecular particles on the membrane vesicles have an increased degree of freedom compared to the molecular particles in the water droplet, and accordingly their potential energy has a tendency to decrease. The outermost electrons of an atom can be regarded as freely flowing particles on the membrane vesicle. The part of the atom except for the outer electrons is called the "ion core". When the ion cores are arranged in an orderly manner into a plane and two planes of ion cores are leaned together in parallel, all the outermost electrons of the atoms can obtain a vast two-dimensional activity space (larger than the proportional space for humans to move on Earth). For electrons, it is a three-dimensional space that is large enough, but the electron cloud or wave function determined by four quantum numbers is the basic carrier for carrying novel quantum states, and the scale of the electron cloud / wave function is equal to the scale of the atom. Therefore, the two-dimensional structure of the atom is the two-dimensional structure of the electron cloud / wave function. For a single electron or electrons forming a Cooper pair, it can also be regarded as a three-dimensional space structure. Especially for Cooper pairs, due to their own "demagnetization" effect, they get rid of the magnetic control of the atomic nucleus, and the corresponding three-dimensional space is upgraded to a four-dimensional spacetime.

[0069] This application provides a simplified quantum field structure for testing observations, also provides the possibility for the prediction of novel quantum physical phenomena in a simple and stable many-body quantum scenario, and also provides a precursor for the manufacture of micro-nano quantum functional devices.

[0070] Through the canonical positioning of the laser magneto-optical trap - artificial superlattice, M atoms with larger electronegativity are located on the middle symmetry plane, while A atoms with smaller electronegativity are arranged in one-to-one correspondence on both sides of the symmetry plane. For the electron clouds entangled between A and M, the gravitational force of the M atom / ion core is stronger, and the electron cloud will move closer to the M atomic nucleus and deviate from the A atomic nucleus at the same time. As a result, the electron cloud of the A atom becomes thinner, showing the characteristics of positive ions. To balance, the centroid (atomic nucleus) of the A atom will also move in the direction of the electron cloud movement and approach the centroid (atomic nucleus) of the M atom, thus causing an endogenous pressure effect. A large number of M nuclei are on one plane, and for the A nucleus plane parallel to it, the atomic positions between the planes are in one-to-one correspondence. Then the A nucleus plane will move closer to the M nucleus plane as a whole. In this way, the A nucleus planes on both sides of the M nucleus plane move closer to the middle layer at the same time, showing an overall "sandwich effect".

[0071] The direct effect of the sandwich effect is that the interlayer distance of A - M - A is smaller than the atomic layer thickness in its elemental state, and the thickness of the whole molecule becomes thinner. That is to say, overall, the total thickness of the three-layer atoms of A - M - A entangled together is smaller than the sum of the thicknesses of 2 layers of A atoms and 1 layer of M atoms in their elemental states. Obviously, the greater the electronegativity difference between M and A, the more significant this thinning degree is. Nevertheless, since both M and A are metal elements, the bond between their atomic layers is still alloy-like and will not form ionic bonds like between metals and non-metals. At the same time, their layered arrangement structure is more ordered than the grain interlocking structure formed by the three-dimensional disordered layer geometry stacking of general alloy phases.

[0072] If viewed from the perspective of the result of the interaction between the atomic nucleus and the extranuclear electrons of an atom, since the mass and positive charge of an atom are concentrated in the atomic nucleus, and the density of the positive charge is much larger than that of the negative charge (the nuclear volume is 10 -15 , that is, one quadrillionth), the extranuclear electron group not only accounts for a very small proportion of the mass (about 1 / 1836 - 1 / 4000 of the entire atomic mass), but also the negative charge distribution used to shield and balance the nuclear positive electric field is extremely loose compared with it. Therefore, the atomic nucleus has an absolute dominant role in the extranuclear electrons. In particular, the atomic structure formed by the dominant role of the nuclear electromagnetic field on the electron group electromagnetic field, and even the condensation and entanglement structure between atoms and atoms, can be regarded as the result of the "electromagnetic programming effect" of the atomic nucleus on the electron group. This control effect of the atomic nucleus on the extranuclear electrons can be abbreviated as "nuclear programming".

[0073] Nuclear programming, in an atom, is manifested as the four quantum numbers of electron arrangement and the electron orbital levels of the atom, and at the same time also follows the principle of the lowest Gibbs free energy and satisfies the gauge symmetry.

[0074] The arrangement of the four quantum numbers determines the energy level distribution of electrons. As a quantization standard tool, the energy level is like the steps in a corridor, with definite and unchanging numerical values. The four quantum numbers are specifically the principal quantum number n, the angular quantum number l, the magnetic quantum number m, and the spin quantum number ms. s The principal quantum number refers to the main energy level n of electron arrangement, which determines the period number of the atom in the periodic table and the maximum number of electrons that can be filled in this level, which is 2n². 2 For example, the electron main levels of the iron Fe atom are divided into 4 layers, belonging to the 4th period. The first element in the same period is potassium K, and the last one is krypton Kr. The angular quantum number l refers to the sub-level number of electron arrangement in a certain main level, which determines the group number of the atom. For example, the outermost electron of the potassium K atom is 4s. 1 K belongs to the elements of the 1st main group (ⅠA). Similarly, the outermost electron of the calcium Ca atom is 4s. 2 Ca belongs to the elements of the 2nd main group (ⅡA). The outermost electron of the gallium Ga atom is 4s. 2 4p 1 Ga belongs to the elements of the 3rd main group (ⅢA), and so on.

[0075] However, between Ca and Ga, there continuously appear 10 so-called "sub-group (ⅠB~Ⅷ) elements", namely scandium Sc, titanium Ti, vanadium V, chromium Cr, manganese Mn, iron Fe, cobalt Co, nickel Ni, copper Cu, and zinc Zn. The reason is that between the 4s and 4p sub-levels, there is also a 3d sub-level, whose energy level is not below the 4s sub-level, but instead the energy level of the 4s sub-level is below the 3d sub-level. This is a strange anomaly. From the perspective of nuclear programming, there is a symmetry breaking between the 3d and 4s energy levels.

[0076] If a single atom is regarded as a "water droplet" in space-time, a suspended water droplet always tries to maintain a spherical shape to minimize its volume and surface area, that is, the surface tension makes the water droplet spherical. The surface tension of the atom to maintain a spherical shape comes from the orbital shape, and the orbital shape is determined by the angular quantum number: among the known s, p, d, and f four orbits, s is spherical and has the highest degree of symmetry. p is a cubic structure and can maintain uniformity in three-dimensional space. Its symmetry basically satisfies rotational symmetry, and there is no eccentricity in the high-speed rotation state. Although its symmetry is slightly lower than that of the s orbit, the difference between the two is not significant. Especially the s + p mixed state shows a highly near-spherical shape and very high symmetry, which does not affect the free rotation of the atomic nucleus and the overall atomic structure. Therefore, the s + p mixed state becomes the most common atomic stable state. Except for the helium He element, the outer electron configurations of all other inert elements are s + p mixed states, that is, the so-called "8e stable structure".

[0077] However, the 5 d-orbitals in three-dimensional space have 5 stretching directions, and the 7 f-orbitals have 7 stretching directions. Their electron clouds cannot be evenly distributed in space and cannot maintain the rotational symmetry of the atom. When they appear in the outermost space of the atom, they will form the so-called "precession" of the atomic rotation axis, just like the rotation of the axis of a gyroscope in a state of slow rotation speed, making the atom unable to maintain the lowest free energy state, thus becoming a high-energy state. In order to maintain its lowest free energy state as much as possible, the nuclear programming mechanism has to be adjusted accordingly, so that the electrons that should originally be arranged in the 3d orbit preferentially enter the 4s orbit for arrangement, thus maintaining the spherical shape of the atomic appearance. On the premise of maintaining this shape, when there are more electrons, they are gradually filled in the 3d orbit. Before the 3d orbit is filled, there are obviously gaps inside this orbital shell, becoming internal structural defects of the atom itself. Therefore, for the atoms of Group B elements, under the competition and reconciliation mechanism between the nuclear programming rules and the surface tension caused by the symmetry orientation, the external nearly perfect spherical shape covers the internal symmetry breaking, leaving nuclear programming defects. Obviously, this symmetry breaking will be revealed when the atom is subjected to a certain excitation, such as the phenomena of heat and cold, isomerism, magnetism, and color change that occur when the atom forms a ligand complex, which are manifestations of electron transition, structural symmetry breaking, and reconstruction during energy level alternation.

[0078] For the atoms of the subgroups and rare earth elements in the 5th, 6th, and 7th periods of the periodic table, there are such nuclear programming defects in the outer d-orbitals of the atoms. This kind of defect further extends to the f-orbitals of each transition element, that is, in the main layer with all 4 types of subshell orbitals s, p, d, and f, if the electrons cannot fill the entire main layer, the filling order of the electrons will be filled in the subshell order of ns~(n-1)d~(n-2)f~np in turn, that is, the rotationally asymmetric d and f subshells must be covered under the outer layer constructed by the rotationally symmetric s or p subshells. This trend is so strong that even if it spans 2 or even 3 main layers, it has to maintain the "spherical face" and cover the "non-spherical internal defects". Judging from the structure of the periodic table, the atoms of subgroup elements are all atoms with defective internal electron filling structures, that is, in the electron arrangement in the outer space of the atom, the d and f orbits are not full and there are gaps. On the contrary, the atoms of main group elements are relatively perfect, that is, not only the outer shell (s orbital or s + p orbital) naturally presents a spherical shape, but the inside is also full and substantial, regardless of whether there are d and f electrons.

[0079] The inner orbital electron filling structure of main group element atoms is defect-free and has the highest shielding ability for nuclear programming, enabling nuclear programming to mainly act on the shell electrons outside the ion core through electrostatic interaction, resulting in a very distinct variation in atomic properties: Alkali metals and alkaline earth metals become "electron-rich atoms". Due to the good shielding ability of the inner electron cloud for the atomic nucleus, the outermost 1-2 electrons have very high degrees of freedom and are very easy to lose, showing very active element properties, large atomic radii, and significant atomic membrane vesiculation; as the atomic number increases, crossing the d sublayer of the next outer layer and even the f sublayer of the second next outer layer to have a p sublayer, the atomic symmetry degree decreases, the electromagnetic shielding ability of the inner electron cloud for the nucleus weakens, the electromagnetic binding force of the outer electrons by nuclear programming increases, it becomes more and more difficult to lose electrons, and the atom becomes more and more inclined to attract electrons to form a full s + p structure, that is, an 8e outer layer structure, achieving a high symmetry of nearly spherical shape. Thus, as the atomic number increases, the electronegativity of the atom increases until the noble elements, and the atoms themselves become nearly perfect full s + p orbital structures. The outer electrons are neither easy to lose nor need to supplement electrons from elsewhere. Therefore, the chemical properties of noble elements are the most stable.

[0080] From the perspective of nuclear programming, transition elements cover the internal voids and defects in order to maintain the perfection of the external form. Although the form of main group elements is full inside, the shielding effect of the high symmetry of the ion core on the nuclear electromagnetic field is greatly enhanced, resulting in either the tendency to "lose the excess outer s electrons" or the need to "supplement and perfect the outer p". These characteristics of elements can be regarded as the natural result of the mutual competition between nuclear programming and the law of the lowest free energy of the external form. Compared with the highly concentrated positive charge of the atomic nucleus and the highly dispersed negative charge of the whole atom, the atomic nucleus dominated by strong interaction has a tendency to further attract and aggregate the extra-nuclear electrons to be denser, thus making the atomic volume decrease. This tendency makes all element atoms at temperatures close to 0K have a tendency to aggregate together, and a tendency for atoms to fall to the ground state to form superconductors or superfluids, that is, to undergo BEC phase transition. Comparing this fundamentality of nuclear programming with the effect that the stress change of the outer electron wave function caused by the increase in environmental temperature forms an excited state, and then leads to the deconstruction of the ground state and the disappearance of superconducting and superfluid properties, nuclear programming still occupies a fundamental and dominant position. This can be verified from the measured cosmic phenomenon of the superfluid and superconducting states inside the "super nucleus" formed at a temperature as high as billions of degrees during the formation of neutron stars - this also hints from a phenomenological perspective that ultra-high pressure is a condition for promoting superconductivity.

[0081] In ordinary chemical reactions, between active metals and active non-metal atoms, one has the need to get rid of the excess, and the other has the need to fill in the deficiency. The two hit it off. The metal atoms that lose electrons become positively charged positive ions, and an ionic crystal structure with electrostatic attraction as the basic force is formed between them and the non-metal atoms that gain electrons to become negative ions; since the gain and loss of electrons are in one-to-one correspondence, the ratio of atomic combination in the formed molecule is also determined. For example, the atomic ratio of metal to non-metal in NaCl is 1 / 1, the atomic ratio in Na2O is 2 / 1, the atomic ratio in CaCl2 is 1 / 2, and so on. However, the interaction between alloy atoms is quite different. Due to the small difference in electronegativity, among the two or several elements of the alloy, no element has the ability to attract electrons so strongly as to completely capture the outer electrons of other alloy elements to become standard negative ions, nor can any atom completely get rid of its outer electrons to become a standard positive ion. An alloying reaction different from that between metal and non-metal atoms occurs between atoms with large electronegativity and atoms with small electronegativity. This reaction is as follows: in the effective action range environment of different nuclear programming, different metal atoms approach each other, the electron clouds of the outer orbits overlap, and then due to the difference in electronegativity, the electron clouds gather towards the atom with large electronegativity. The atom with large electronegativity forms a negative charge end, and correspondingly, the atom with small electronegativity becomes a positive charge end. The two form a polar molecule or a segregated molecule, but there is no obvious ratio determined by positive and negative charge integers like that between metal and non-metal. Even compounds between metals and metals are not called molecules, but alloys or intermetallic compounds. Correspondingly, the theory of combination between metal element atoms is called alloy theory. The alloy theory developed by using statistical physics and mathematical methods, based on the solution model, has formed the elements and concepts such as the structure and strengthening mechanism of alloys such as solid solution, second phase, and dislocation.

[0082] The alloy theory established by statistical thermodynamics methods is insufficient in describing the change process and mechanism of the microstructure of alloy compounds based on spatial coordination and the merging of atomic outer electron orbits to form molecular orbits. With the in-depth development of the ability to control the microstructure to the manipulation of individual atoms, the theory of microstructure change is accelerating its creation and improvement with the cooperation of ultra-cold vacuum technology. Among them, the spatial geometric structure of atomic combination has become the key to describing the formation of multiple phases in alloys.

[0083] Between two metal atoms with different electronegativities, since there is no condition for electron gain or loss, their spatial combination state is not based on the integer ratio between positive and negative ions, but on the coordination combination state between their elemental atoms, forming body-centered cubic, face-centered cubic, close-packed hexagonal, tetragonal and other lattice structures. A relatively typical combination structure of metal elements is the face-centered cubic structure, which follows the principle of closest packing and has a coordination number of 12. For example, gold, silver, copper, and aluminum all have face-centered cubic structures. When one metal is used as a solvent and the other as a solute, they are basically a homogeneous dispersion system in the molten state, but the solidified state varies greatly because of the "solubility" problem.

[0084] When solute M forms a solidified state in solvent A, if the solubility is very large, such as infinite, then A and M will form an infinite solid solution, such as Cu-Ni, Ti-Zr, Mg-Cd, Au-Ag, etc.; if the solubility is very small, the excess solute will segregate and agglomerate during solidification and cannot form a homogeneous phase with the solvent. The excess solute and the solvent often form a discontinuous A x M y binary alloy compound. And the so-called dissolution is essentially that the solute can be coherent with the lattice points of the solvent, that is, M can replace the position of A in the three-dimensional space lattice points of A, or M can be filled into the voids between the three-dimensional space lattice points of A without changing the original coordination number of the lattice points. Although the coordination number remains unchanged, due to the differences in atomic radius and electronegativity, whether M replaces A or fills into the lattice voids of A, it causes lattice distortion. As the distortion degree increases to a certain value, the lattice continuity of A can no longer be maintained, that is, incoherence occurs. At this time, it corresponds to the saturated solubility value of M in A. From the perspective of the "inverse square law" of gravity and system expansion and contraction, only when the product of the electronegativity (gravity) of M and the square of its own atomic radius is the same as the product of the electronegativity of A and the square of its own atomic radius, when M and A are combined in three-dimensional space, the two atoms have the same attraction for the electrons at the junction, and there will be no volume change of both atoms, which is conducive to the formation of an infinite solid solution. However, this situation is extremely rare, so it is very rare for solute M and solvent A to be infinitely miscible.

[0085] There is a situation where when the atomic radius r M <r A but the difference is not large, and the electronegativity e M >e AWhen considering the dissolution process of M in A as the proportion of M atoms that can replace A atoms in the A lattice, from a spatial geometry perspective, the face-centered cubic structure of A is equivalent to a configuration where an atom A0 is at the center of a sphere, 12 A coordination atoms are evenly distributed on the spherical surface, every 4 atoms form a plane with the central atom, and the three planes are pairwise orthogonal, with the intersection of the three planes being the central atom. Such a configuration has the highest symmetry in the spatial electron cloud distribution, thus the lowest free energy and the most stable structure. When one A is replaced by M, the 12 A atoms on the three orthogonal planes centered on M immediately face a choice: that is, r M <r A and the gravitational force of M is greater than that of A. The resulting contraction effect is like a trap, making it easier for adjacent A atoms to be replaced by M. And as long as one more A is randomly replaced by M, the two planes where these two M atoms are located will form a low-potential energy surface, which has the advantage of attracting the next M to replace the remaining A atoms on this plane. Such advantages will form a superposition effect. As the substitution effect continues, this plane also forms an aggregation plane of M atoms, and this plane will continue to expand until the A steric hindrance caused by lattice distortion makes the M atoms at the edge no longer able to maintain a coherent relationship with the adjacent A, and the M plane stops growing. The other two planes orthogonal to this plane cannot compete with it and can only maintain the A lattice grid unchanged, but are also affected by the contraction of the M plane on the orthogonal line.

[0086] Since there are d-orbital defects in M atoms, as the electron cloud of A is supplemented, this kind of defect will be compensated to a certain extent. Moreover, the formation of the atomic layer plane of M directly feedback affects the spin state of the main body of its nuclear programming - the M atomic nucleus, that is, the spin synchrony on the two-dimensional plane. This synchrony focuses on making the spin state of the atomic nucleus consistent with the symmetric plane, that is, the rotation axis of each nucleus is as perpendicular as possible to the common plane of the M atomic group. This, in turn, will prompt more degenerate states of the d orbitals of M atoms to converge on the common plane. That is to say, the endogenous symmetry breaking of M atoms in the three-dimensional state of full freedom is corrected to a certain extent in the two-dimensional plane state composed of the same kind of atoms. Since the enhancement of symmetry is equivalent to the reduction of energy, this process is prone to occur spontaneously at low temperatures; at the same time, it is easy to infer that the common plane of the M atomic group bears the flat-band structure with a high-density electron cloud.

[0087] Due to the establishment of the new symmetry, the M atoms and the cluster plane layer they form are in a state of low Gibbs free energy. This state is more stable than the multi-crystalline disordered layer structure formed by M piling up in a three-dimensional volume with an average scale of 100 μm - which is a common phenomenon in industrial alloy production - at a certain temperature.

[0088] In summary, a magneto-optical trap laser superlattice matrix is artificially created. An atomic gas is evaporated by laser pulses, and a corresponding optical tweezer is used to control and push individual atoms into the magneto-optical trap laser superlattice matrix, in accordance with (AMA) N , (A…AMA…A) N or (A…AMMA…A) N is assembled in a symmetric sandwich layer manner, which has the feasibility of generating a new type of molecule with an alloy alkene molecular structure, an endogenously extensible electron cloud flat band, and further evolving into a two-dimensional material with molecular delocalized orbitals.

[0089] The "micro-nano interface manufacturing" method of using optical tweezers to drive atoms to assemble in a magneto-optical trap superlattice solves the contradiction between the demand for alloy ordering manufacturing and the relatively crude existing industrial production technology, representing the direction of future new materials.

[0090] During the above-mentioned metal quantitative filling process, active temperature control is adopted to achieve directional and quantitative filling of the metal. Compared with the traditional filling method, not only the quantitative control of the filled metal is realized, but also the filling consistency is improved.

[0091] For two-dimensional planar or film-like (A…AMA…A) N / (A…AMMA…A) N macromolecules, if the structure is not stable enough at a certain temperature, first consider the internal electromagnetic balance. Due to the strong correlation of multiple factors such as d-orbital filling, volume contraction, and redistribution of positive and negative charge space density, which belongs to the chaotic process of self-organized criticality, first help the internal electromagnetic rebalance of the molecule by adding or subtracting electrons to the system.

[0092] For two-dimensional planar or film-like (A…AMA…A) N / (A…AMMA…A) N macromolecules, monolayer or multilayer graphene can be used for packaging. Since graphene products and technologies are already mature, they have a stable room-temperature microstructure and physical and chemical properties, and excellent electromagnetic characteristics. After packaging this type of alkene molecule, atomic interference is relatively neutral, and the strange properties of the alkene molecule itself can be transmitted outward through the "coating" of graphene by the quantum tunneling effect (Josephson effect). This also provides convenience for the assembly of graphene-coated (A…AMA…A) N / (A…AMMA…A) N alkene macromolecular sheets or blocks, making this type of molecule carrying novel quantum effects have the industrialization attributes of both mass production and arbitrary assembly.

[0093] Quantum tunneling or the Josephson effect can further prompt the flat band of the endogenous extended electron cloud in the molecule to cross the molecular boundary and achieve natural connection with the flat band of the electron cloud of adjacent molecules, so that the entire two-dimensional material is penetrated by the endogenous extended electron cloud flat band structure.

[0094] Dangling bond decoration of functional atomic groups on alkene macromolecules or their graphene coatings can, on the one hand, increase the stability of the molecular system and endow brittle coated graphene with elastoplastic characteristics. On the other hand, it is also a means of exciting molecular specific energy. Using this method, it is possible to create an infinite number of novel quantum excited states.

[0095] The ultra-cold and ultra-quiet environment required for the single-atom assembly preparation of alkene alloy macromolecules is a prerequisite. Because only at extremely low temperatures close to 0K can the activity of various atomic substances be greatly reduced, so much so that the speed of light can be reduced to less than 1 m / s. In such an environment, the preparation process of molecules can achieve absolute purity and absolute cleanliness without interference from other unexpected heteroatoms. In such an environment, heteroatoms in the atomic gas can also be accurately and effectively excluded by optical tweezers, so that only atoms M and A fall into the magneto-optical trap laser superlattice matrix, thus providing good conditions for manufacturing "absolutely pure" (A…AMA…A) N / (A…AMMA…A) N alkene macromolecules.

[0096] With the successful development of various (A…AMA…A) N / (A…AMMA…A) N alkene macromolecules that meet the design expectations, it is possible to establish a gene library of various molecular templates, an intelligent management and parameter supply database for various paired diatomic atoms and the required laser photons, optical tweezers tools, magneto-optical trap laser superlattice matrices, etc., and a factory that supports the production of two-dimensional alkene state macromolecular materials for various paired diatomic atoms can be built; especially the "copy-paste" or "hollowing-insertion" manufacturing technology based on molecular templates can further support the large-scale production of such alkene molecular two-dimensional materials to meet social needs.

[0097] Advantages of the present invention:

[0098] The present invention applies the principle of symmetry breaking and the method of two-dimensional reconstruction of atomic condensed matter to propose a novel two-dimensional material and its molecular structure, and through the preparation method of the novel two-dimensional material and its molecules, summarizes, applies and refines scientific data and cutting-edge technologies, and provides a principle method and framework for opening up cross-scale detection of novel quantum effects between the microscopic and macroscopic scales.

[0099] The present invention provides a new direction for solving the existing problems in the development and manufacturing of new materials with macroscopic quantum effects (including new electromagnetic materials, two-dimensional materials, and superconducting materials): ① It realizes the ultra-high pressure P pursued in the unconventional superconducting mechanism theory at high temperature or room temperature. S , the large specific surface area F required for the electron long-wave mean free path S , molecular coherence wavelength L cw ① The unity of factors such as sufficiently large in the "alkene-type two-element two-dimensional alloy molecule with symmetrical sandwich layer electron cloud" creates the most sufficient conditions for the formation of molecular delocalized orbitals; ② The room-temperature superconducting or "water-temperature superconducting" new materials are studied and trial-produced by optical tweezers to control single-atom assembly and magneto-optical trap superlattice regulation, which provides almost unlimited possibilities for the research and development of new two-dimensional materials; ③ The correlation between the electroacoustic coupling mechanism and the electronic flat band structure, and the shielding effect of the electronic flat band structure on the factors that interfere with coupling in the material, ④ The correlation between the superconducting transition temperature Tc and the equivalent pressure in the intrinsic extensional electron cloud flat band; ⑤ The stability of the symmetrical sandwich layer alkene-type binary alloy molecule and the stability of its intrinsic extensional electron cloud flat band structure are tested, opening up a new way to effectively control the electronic state (cloud structure and its long-wave free path) in the material.

[0100] The present invention directly expands the special microscopic quantum state of the "naturally discovered" electronic flat band (EFB) and its compact localized state (CLS), in which the electrons are only confined to a few adjacent lattice points, the wave function is highly localized, and the radius is within 1 nanometer, into an artificially manufactured atomic combination containing more than a million atoms, and spontaneously and consistently evolves into a super-large two-dimensional molecular structure through atomic coherent waves. Then, this molecular structure is used to manufacture two-dimensional materials through a splicing and lamination method, so that the molecules can use the quantum tunneling effect at the edge to transfer their own endogenous extensional electrons. The cloud flat belts (FBOEC) are connected to each other to become a macroscopic quantum state that runs through the material system, realizing the leap from mathematical models to the actual creation of new materials with special functions; at the same time, in each intermediate link of "molecular manufacturing" and "material manufacturing", through operations such as "adding and subtracting electrons", "graphene packaging", and "functional group suspension", it is possible to achieve molecular stability regulation and molecular excited state regulation, construct various functional components required for electromagnetic systems and semiconductor systems, and cover the nanometer to micrometer to millimeter scales, further realizing the leapfrog link between macroscopic material performance and microscopic structure.

[0101] The present invention, by virtue of the rotational symmetry of the intramolecular atomic saturated coordination bonds, the extensibility of the endogenous electron cloud flat band, and the ductility of the macroscopic two-dimensional material formed by splicing and laminating, solves the practical problems such as the small size of current two-dimensional materials, high manufacturing costs, and difficulties in developing industrial production process technologies. Most of the graphene and other two-dimensional materials currently developed for research are molecular structural units mainly composed of covalent bonds or weak ionic bonds. Due to the directionality of the atomic bonding between atoms, the macroscopic mechanical properties of the manufactured materials are brittle and lack ductility. This problem can be readily solved after the present invention uses saturated coordination bonds to solve the problem of expanding the molecular large plane.

[0102] The present invention, in response to the current hot research on metalenes, focuses on the strange quantum states that may be generated by the lack of coordination state of internal atoms in the research of metalenes. The two-dimensional material with an endogenous extensible electron flat band, namely the alkene-type alloy molecular material with a symmetric sandwich layer concentrating electron clouds in the present invention, focuses on the macroscopic quantum state of the internal flat band structure. Such comparable research will provide rich practices for the effective control of electron movement, cloud structure, and its long-wave free path in materials, and promote the creation and development of advanced material theories.

[0103] In summary, the present invention, by virtue of the rotational symmetry of the intramolecular atomic saturated coordination bonds, the extensibility of the endogenous electron cloud flat band, and the ductility of the macroscopic two-dimensional material formed by splicing and laminating, solves the practical problems such as the small size of current two-dimensional materials, high manufacturing costs, and difficulties in developing industrial production process technologies.

[0111] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0112] Embodiment 1:

[0113] A two-dimensional material capable of endogenously extending ductile electron cloud flat bands, where the material molecules are composed of transition element atoms Cu and main group active metal element atoms Al, combined into a two-element three-layer sandwich planar macromolecule with the structure of (AlCuAl). N In the interior of the macromolecule plane, the coordination number of Cu atomic layers is saturated coordination 12. At the edge of the molecular plane, the coordination number of Cu atoms ≤ 12. The subscript N is a natural number ≥ 4, representing the number of atoms of the same kind in each layer of the macromolecule; N increases according to the Fibonacci numbers. For example, N can be selected as 5 / 9 / 14 / 23 / 37 / 60 / 97 / …… until the size of the entire molecular plane (if the molecular plane is circular, it refers to the diameter; if the molecular plane is square, it refers to the side length) reaches the millimeter level.

[0114] Preferably, the molecular size is greater than or equal to 10 nm.

[0115] The transition element M can also be an element in the B subgroup, group VIII, rare earth RE inner transition elements, and actinide elements in the periodic table.

[0116] The active main group elements can also be metal elements with chemical activity (or the ability to lose electrons) greater than or equal to that of copper Cu, such as lithium Li, sodium Na, potassium K, rubidium Rb, cesium Cs, beryllium Be, magnesium Mg, calcium Ca, strontium Sr, barium Ba, aluminum Al, gallium Ga, indium In, thallium Tl, silicon Si, germanium Ge, tin Sn, lead Pb, antimony Sb, bismuth Bi;

[0117] Preferably, for the active main group elements, the outer electron structure of the atoms satisfies ns + np ≤ 3.

[0118] Preferably, the Al-Cu alloy molecular structure is composed of transition element Cu and main group active metal element atoms Al, combined into (AlAlCuAlAl). NA dual-element five-layer sandwich planar macromolecule with a structure of (N≥6), or combined into (AlAlAlCuAlAlAl) N A dual-element seven-layer sandwich planar macromolecule with a structure of (N≥8), or a dual-element multi-layer sandwich planar macromolecule with more layers having a Cu atomic layer as the symmetry plane and the same number of Al atomic layers on both sides (Al…AlCuAl…Al) N [N≥(total number of Al and Cu atomic layers + 1)].

[0119] Preferably, the electronegativity e of the transition element atom Cu The value (ability to attract electrons) is higher than the electronegativity e of the main group active metal element atom Al The value, that is, e Cu >e Al .

[0120] Preferably, the volume (or atomic radius r Cu ) of the transition element atom is smaller than the volume (or atomic radius r Al ) of the Al atom of the main group active metal element, that is, r Cu <r Al .

[0121] Preferably, through temperature regulation and lattice constant regulation between the lattice points of the magneto-optical trap superlattice, the transition element Cu atoms and atomic layers pull the outer electrons and electron clouds of the Al atoms closer to themselves by exceeding the electronegativity of the Al atoms, causing the electron clouds to gather towards the geometric center plane of the molecule and increasing the negative charge density. Furthermore, the symmetric Al atomic layers on both sides synchronously approach the middle layer, reducing the layer spacing and the volume enclosed between the layers. As a result, the energy band density and electron density of each atom are further increased, and the fluctuation potential energy of the electron clouds inside the molecule is increased, which is equivalent to an increase in the pressure between the atomic layers and an enhancement of the vibration energy level. Corresponding Figure 3 and Figure 7 , it can be calculated that: in the ambient temperature and pressure environment, the volume contraction effect of a single Cu atom is equivalent to being under a pressure of 650,000 atmospheres. Due to the corresponding contraction of the Al atom volume caused by the Cu atom contraction, the effect is equivalent to being under a pressure of 80,000 atmospheres.

[0122] The aluminum-copper Al-Cu alloy molecular structure in this embodiment is called an alkene-type aluminum-copper Al-Cu alloy molecular structure with symmetric sandwich layer extraction of electron clouds. The degenerate state structure of the outer d electron orbit of the Cu atom is reconstructed. The result of the reconstruction is that in d z 2 、d x 2 -y 2The electron cloud density increases within the region on the orbit whose stretching direction is consistent with the xy plane of the Cu atomic layer, and a high-density electron cloud extended flat band structure that is overall continuous and uniform is formed on the (xy) N plane of all degenerate Cu atomic layers. When the value of N reaches a certain large number (such as 10 6 or more), macroscopic effects will be caused, such as a circular current running on the large surface of the molecular layer and a molecular magnetic moment perpendicular to this circular current.

[0123] Preferably, the sandwich layer Cu atoms are double-layer. Correspondingly, the original alkene molecular structure has (AlCuCuAl) N , (Al AlCuCuAlAl) N , (AlAlAlCuCuAlAlAl) N , (Al…AlCuCuAl…Al) N [N≥(number of Al layers + 2 + 1)].

[0124] Preferably, when the value of N is large enough to affect the stability of the molecular plane, the molecular plane can be stabilized by removing one or more electrons from the molecular system, or by adding one or more electrons to the molecular system. This method can also be used to test the stability of the alkene molecule.

[0125] Preferably, it can exist in an ultra-cold temperature environment close to 0K and a laser superlattice field formed by an optical tweezer. The proof of its existence is that characteristic coherent states are formed between the layers of the molecule, and characteristic interference states are also formed between the atoms. The characteristic coherent states lead the same type of atoms in the same layer to gather towards the center, and at the same time lead the different atomic layers to approach each other, forming an overall aggregation trend. This aggregation trend is ultimately resisted and balanced by the enhancement of the Coulomb repulsion caused by the increase in the electron cloud density. At the equilibrium state, the characteristic coherent states of the atoms in the same layer degenerate, that is, homomorphic vibration (resonance) is achieved.

[0126] Preferably, for a molecule in an equilibrium and stable state in an ultra-cold environment, the molecule can be packaged with graphene. After the graphene packaging is completed, the magneto-optical trap laser superlattice can be removed. After the magneto-optical trap laser superlattice is removed, the stability of the molecule can be tested by heating and pressurizing. Through the stability test, the molecular types and their size ranges that stably exist in an atmospheric pressure environment above 200K can be selected. Further, the molecular types and their size ranges that stably exist in an atmospheric pressure environment of 300 - 400K (or room temperature to boiling water temperature) can be selected.

[0127] Preferably, alloy alkene molecules wrapped by graphene and stably existing in the natural state on the earth's surface can be spliced with each other. The splicing methods can be the splicing of plane edges, the coaxial stacking and thickening, or after the coaxial stacking and thickening, the edge-to-edge splicing of the stacked macromolecules of the same thickness, or after splicing into a larger planar structure, the stacking and thickening of molecular combinations of the same area.

[0128] Preferably, alkene molecules combine with other atoms or atomic groups through the hanging bonds of edge or surface atoms to form a rich surface hanging structure state.

[0129] A preparation method of a two-dimensional material with an endogenously extensible electron cloud flat band. Under a certain temperature and pressure environment, through the assembly operation of atomic ordering, the atoms of two elements, Al and Cu, are coordinated in a sandwich layer manner with the Cu atomic layer as the symmetric layer and the Al atomic layers symmetrically arranged on both sides of the Cu layer. Along the expansion of the layer plane, the molecular structure of the material is in a two-dimensional state, and then the two-dimensional material is prepared by using the two-dimensional state molecules.

[0130] Preferably, in an ultra-cold environment close to 0K (-273.15 °C), free-moving single atoms are captured in a vacuum by laser photons or laser pulses injected into a vacuum cavity to make the atoms move directionally, or counteracting synchronous lasers are used to keep the atoms stationary. Further, the atoms are positioned and filled in a magneto-optical potential well, that is, an optical lattice, constructed by three-dimensional six-directional lasers. In a matrix with N laser superlattice grids in each layer, the Al atomic layer and the Cu atomic layer are arranged according to the aforementioned molecular structure to form N the (AlCuAl) N structure, the (AlAlMCuAlAl) N structure, the (AlAlAlCuAlAlAl) N structure, or more layers, that is, the symmetric sandwich layer structure of (Al…AlCuAl…Al).

[0131] Preferably, single atoms in the vacuum cavity are prepared and supplied through an atomic gas chamber-optical tweezer matrix system with quantitative metal filling.

[0132] Preferably, the atomic gas chamber-optical tweezer matrix system includes: an optical tweezer matrix and the atomic aggregation vacuum chamber where it is located, multiple atomic gas chambers, metal Cu and metal Al dispensing containers, that is, Cu atomic gas and Al atomic gas generating containers, a vacuum pumping system, a temperature control system, a multi-functional laser device, a vacuum valve for connecting the atomic gas chamber to the atomic aggregation vacuum cavity where the optical tweezer matrix is located, and a vacuum valve for connecting the atomic gas chamber to the atomic gas generating container, that is, the metal dispensing container.

[0133] Preferably, laser evaporation of metal atoms is performed to strip them from the condensed state; three-dimensional laser guiding or positioning of single atoms, atomic clusters, or molecules; constructing a magneto-optical trap superlattice matrix; detecting characteristic coherent waves between atoms and atomic layers in the matrix molecules; performing output conversion and display of the detection signals; all are achieved by adjusting the frequency and period of the laser pulses output by the multifunctional laser device.

[0134] Preferably, the atomic gas generation container, which is also the metal packaging container, contains a pure elemental metal and is equipped with thermal evaporation, laser evaporation, and pushing devices, enabling the condensed metal to become atomic clusters (molecules) or single atoms and pushing the atomic clusters (molecules) or single atoms to the magneto-optical trap superlattice matrix directionally.

[0135] Preferably, by actively and precisely controlling the temperature distribution in the metal packaging container and combining with the laser evaporation technology of atoms, the generation of atomic gas of metal, the capture, directional pushing, directional deposition, positioning, and regulation of the condensed entanglement state of atoms are realized.

[0136] Preferably, the rate of mass decrease of a certain atomic gas chamber is used to calibrate the atomic deposition rate, and then the quantitative filling of the metal is realized, or the quantitative filling of the metal is realized by counting laser pulses.

[0137] Preferably, one or more electrons are removed by using the laser photoelectric coupling effect (photoelectric effect) to stabilize the molecular plane, or one or more electrons are added to the molecule by an electron acceleration device (such as strong magnetic field or electron collider acceleration) to stabilize the molecular plane.

[0138] Preferably, using the optical tweezer technology, the alkene-type planar molecule is further laid flat on a graphene planar molecule with the same or similar area. After the laying is completed, another graphene planar molecule with the same area is covered on the alkene molecule. Through the quantum entanglement effect that occurs spontaneously between the graphene molecular plane and the alloy alkene molecular plane at a certain temperature, the graphene packaging of the alkene macromolecule is completed.

[0139] Preferably, the graphene packaging can be carried out in a manner synchronous with the preparation of the aluminum-copper Al-Cu alloy alkene molecules, that is, every time the alloy alkene molecular plane expands one circle, the graphene (carbon atoms) also expands one circle accordingly.

[0140] Preferably, after the molecular weight meets the required N value, a stable state is obtained, and the graphene packaging is completed, the molecule is placed on a smooth graphite plate or a plate made of other materials with neutral physical and chemical properties and a smooth surface, such as a glass plate, a single crystal silicon plate, a silicon carbide plate, etc., to provide spare components for molecular combination and assembly.

[0141] Preferably, it supports a "copy-paste" preparation method or a "hollowing-insertion" preparation method based on a molecular template.

[0142] The steps of the "copy-paste" preparation method are as follows: For the selected (Al…AlCuAl…Al) N or (Al…AlCuCuAl…Al) N symmetric sandwich-layer molecular structure, since the parameter system of the corresponding magneto-optical trap superlattice matrix lattice structure has been determined, at a temperature that ensures the stable existence of the molecule, through the intelligent regulation of the magneto-optical trap superlattice matrix lattice parameters, by first forming a single layer of Al N and Cu N layered molecular template, and then by manipulating the magneto-optical trap superlattice matrix, the single layer of Al N and Cu N are stacked layer by layer, and the required symmetric sandwich-layer molecules can be mass-produced, improving the manufacturing speed and production efficiency; further, (Al…Al) N template, Cu N template and (CuCu) N template can be made first, and (Al…AlCuAl…Al) N or (Al…AlCuCuAl…Al) N alkene molecules can be assembled at any time according to needs.

[0143] The steps of the "hollowing-insertion" preparation method are as follows: Select a pure odd-layer molecular crystal (Al…AlAlAl…Al) N , under certain temperature and vacuum optical tweezer control, use coherent laser pulses to strike the atoms Al in the middle layer, and at the same time fill the holes formed by the ejection of atoms Al with the carried atoms Cu until all the atoms Al in the middle layer are replaced by Cu, and the whole molecular crystal becomes (Al…AlCuAl…Al) N ; similarly, select a pure even-layer molecular crystal (Al…AlAlAlAl…Al) N , use coherent laser pulses to strike the atoms Al in the middle double layer, so that the AlAl double-layer atoms are replaced by the CuCu atom double layer, and the whole molecular crystal becomes (Al…AlCuCuAl…Al) N ;

[0144] The "copy-paste" or "hollowing-insertion" preparation method based on a molecular template can be used to trial-produce an electron cloud sandwich extraction-type binary aluminum-copper Al-Cu alloy alkene molecule with an asymmetric state of the number of Al layers, such as (AlAlAlCuAlAlAlAl) N , (AlAlAlCuCuAlAlAlAlAl) N, and non-Al and non-Cu heteroatoms can be filled into any position in the molecular disk by coherent laser substitution.

[0145] Preferably, such alloy molecules are prepared in an ultracold and ultraquiet environment, such as in the cold and quiet environment of the Earth's South Pole, North Pole or deep cave, or in the extremely cold and ultraquiet environment of the back of the moon or the surface of Mars, or in the environment of cosmic microwave background radiation in outer space.

[0146] Preferably, the alkene-type alloy molecule with symmetrical sandwich layer electron cloud extraction can be magnesium copper Mg-Cu, magnesium iron Mg-Fe, and according to the basic conditions of "transition elements have large electronegativity and small atomic radius, and main group elements have small electronegativity and large atomic radius", one of the following main group elements is selected as the element atom A:

[0150] The atoms of the two elements M and A are used in the form of cold atomic gas according to the aforementioned optical tweezers technology and magneto-optical trap superlattice technology in an ultra-cold and ultra-quiet environment to manufacture alkene-type alloy molecules with symmetrical sandwich layers that extract electron clouds. The alkene-type alloy molecules with symmetrical sandwich layers that extract electron clouds are then used to assemble a two-dimensional material with an endogenous extensible electron cloud flat band through splicing and stacking.

[0151] Preferably, the alkene-type two-dimensional molecule with a symmetric sandwich layer concentrating the electron cloud can be manufactured by selecting two non-metal elements according to the basic condition of "combining an atom with a large electronegativity and a small atomic radius with an atom with a small electronegativity and a large atomic radius". For example, the atoms of fluorine F element and oxygen O element can be combined into (O…OFO…O). N Alkene-type two-dimensional molecular structure.

[0152] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
