Description

Technical Field

[0001] This application belongs to the field of corner devices, and more specifically, relates to a corner device that supports radio frequency transmission. Background Technology

[0002] In extremely low-temperature, high-magnetic-field environments, electrical and thermoelectric transport methods are commonly used to study the motion of quasiparticles under external excitation to obtain material properties. However, employing acoustic-electric transport to study the intrinsic properties of materials provides a completely new measurement tool for physics research, allowing for the acquisition of even more information about the materials' properties.

[0003] Studying materials using acoustic-electric transport methods typically requires the introduction of multi-dimensional radio frequency (RF) signals. However, introducing RF signals in extremely low-temperature, high-magnetic-field environments presents numerous challenges: Firstly, GHz RF signal transmission requires semi-rigid coaxial cables or very thick flexible coaxial cables, and traditional connection methods cannot achieve angular rotation of the sample. Secondly, the measurement environment in extremely low-temperature, high-magnetic-field conditions is extremely confined, lacking sufficient space for the RF transmission line to accommodate bending and twisting radii. Furthermore, at low temperatures, high-frequency coaxial cables become even stiffer and more difficult to rotate. Based on these issues, it is evident that existing structures have poor applicability in extremely low-temperature, high-magnetic-field environments, significantly limiting their application in materials research. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a corner device that supports radio frequency transmission, aiming to solve the problem that existing structures have poor applicability in extremely low temperature and strong magnetic field environments, which leads to significant limitations in materials research.

[0009] The cornering device also includes an RF connector for transmitting RF signals to the sample on the sample mounting tray.

[0010] Compared with the prior art, the above-described technical solution conceived in this application allows for the following advantages when using the rotating device for sample research: the sample is first mounted on a sample mounting plate. The extension mechanism allows the sample mounting plate to extend into an environment with extremely low temperature and strong magnetic field. The radio frequency connector can transmit radio frequency signals into the sample. By rotating the turntable, the sample mounting plate rotates horizontally to change the angle and position of the sample in the magnetic field. Simultaneously, the drive component can drive the rotating tray and sample mounting plate to rotate to further adjust the position of the sample in the magnetic field. During the movement, the sample can cut the magnetic induction lines in the magnetic field. The sample requires less space during angle adjustment and can achieve multi-angle adjustment, thus achieving beneficial effects suitable for extremely low temperature and strong magnetic field environments.

[0011] As a further preferred embodiment, a signal transmission component for signal transmission is provided between the RF connector and the rotating tray, and the sample mounting plate and the rotating tray are electrically connected.

[0012] By adopting the above technical solution, the RF connector is connected to the rotating tray through the signal transmission component. When the sample mounting tray is connected to the rotating tray, an RF signal can be transmitted into the sample. The sample mounting tray is easy to install and remove, and different sample mounting trays can be installed according to actual use needs, thereby improving installation efficiency and usage effect.

[0013] As a further preferred embodiment, the signal transmission component includes two conductive rods and two connectors. The top ends of the two conductive rods are electrically connected to the radio frequency connector, and the two connectors are electrically connected to the bottom ends of the corresponding conductive rods. The rotating tray is rotatably connected between the two connectors and electrically connected to the connectors.

[0014] By adopting the above technical solution, the RF connector can be connected to the rotating tray through the conductive rod and connector head. After the sample mounting plate is installed on the rotating tray, RF signals can be introduced into the sample. The RF connector can be placed outside the extremely low temperature and strong magnetic field environment to avoid affecting the signal input.

[0015] As a further preferred embodiment, the sample mounting tray includes two interconnected first plates and second plates forming an included angle between them, the first plates being parallel to and connected to the rotating tray.

[0016] By adopting the above technical solution, the first plate is connected to the rotating tray during sample mounting, and the sample can be mounted on the second plate, avoiding accidental contact and damage to the sample when the first plate is installed or removed.

[0017] As a further preferred embodiment, a damping shaft is provided between the first plate and the second plate, and the second plate is rotatably connected to the first plate through the damping shaft.

[0018] By adopting the above technical solution, the second plate can rotate relative to the first plate, thereby moving the sample. This allows for adjustment of the sample's mounting angle and position without needing to replace the sample mounting plate, making adjustment convenient.

[0019] As a further preferred embodiment, the drive assembly includes a drive motor and a first rotating gear disk. The drive motor is fixedly mounted on the extension mechanism and its output shaft is coaxially arranged with the rotation axis of the rotating disk. The first rotating gear disk is fixedly connected to the rotating tray and is coaxially arranged with the rotation axis of the rotating tray. The drive motor drives the first rotating gear disk to rotate through a steering assembly.

[0020] By adopting the above technical solution, the drive motor can drive the first rotating toothed disk through the steering component. The rotation of the first rotating toothed disk can drive the rotating turntable to rotate. The structure is simple, the control is convenient and stable, and it can accurately control the fixed position of the sample.

[0021] As a further preferred embodiment, the steering assembly includes a rotating rod, a second rotating gear disk, a first bevel gear, and a second bevel gear. The rotating rod is parallel to the rotation axis of the rotating tray. The second rotating gear disk is coaxially disposed on the rotating rod and meshes with the first rotating gear disk. The first bevel gear is coaxially fixedly connected to the output shaft of the drive motor. The second bevel gear is coaxially fixedly connected to one side of the second rotating gear disk. The first bevel gear and the second bevel gear mesh with each other.

[0022] By adopting the above technical solution, the drive motor can drive the first bevel gear to rotate the second bevel gear, thereby causing the second rotating gear disk to rotate. After the second rotating gear disk rotates, it can drive the first rotating gear disk to rotate, thereby realizing the adjustment of the angle of the rotating tray and the sample mounting tray. With this structure, the overall length of the device is extended, which can provide more space for the rotating tray and the sample mounting tray.

[0023] As a further preferred embodiment, the sample cornering mechanism further includes a mounting frame with a hollow structure, the mounting frame being fixedly connected to the extension mechanism, the connector and the rotating rod being mounted on the mounting frame, and the rotating tray and the sample mounting plate being located inside the mounting frame.

[0024] By adopting the above technical solution, the mounting frame provides a carrier for the installation of the rotating tray and steering components, making the installation more stable. At the same time, it protects the rotating tray and sample mounting plate, preventing them from being damaged by collisions during the adjustment process.

[0025] As a further preferred embodiment, the extension mechanism includes several extension sleeves, which are connected end to end and are all located on the same axis as the rotation axis of the rotating disk.

[0026] By adopting the above technical solution, the device can be equipped with an appropriate number of extension sleeves according to the actual needs of use, so that the sample can be extended to a suitable position in an extremely low temperature and strong magnetic field environment. The structure is simple and the applicability is better.

[0027] As a further preferred embodiment, each of the extension sleeves is fixedly connected to a heat insulation plate, and the heat insulation plate has a positioning opening for the transmission rod to pass through.

[0028] By adopting the above technical solution, the transmission rod is set through the positioning opening on the heat insulation board, which can improve the stability of the transmission rod, making it more stable after installation. It can move together with the device during adjustment, avoiding interference when the corner device is adjusted, thus avoiding affecting the adjustment effect. At the same time, the heat insulation board can act as a baffle to shield the heat from the upper part to the lower low-temperature part, thus playing the role of a cold shield.

[0029] In summary, compared with the prior art, the technical solutions conceived in this application have the following main technical advantages:

[0030] 1. This application enables the sample mounting plate and the sample to be tested to be extended into an environment of extremely low temperature and strong magnetic field through an extended mechanism. The radio frequency connector can transmit radio frequency signals into the sample. By rotating the turntable, the sample mounting plate can be rotated in the horizontal direction to change the angle and position of the sample in the magnetic field. At the same time, the drive component can drive the rotating tray and the sample mounting plate to rotate to further adjust the position of the sample in the magnetic field. During the movement, the sample can cut the magnetic induction lines in the magnetic field. Using this device, the space required for the sample to adjust the angle is small, and it can realize the adjustment of the sample at multiple angles. It is suitable for environments of extremely low temperature and strong magnetic field, and also provides angle-dependent research for fields such as scanning tunneling ferromagnetic resonance, providing new detection methods and new dimensions for scientific research.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] In metals and semiconductors, the directional motion of electrons can be generated by applying an electrical bias or a temperature gradient. The acceleration of electrons is hindered by scattering with impurities or phonons, resulting in an equilibrium state with a finite potential drop in the system. This transport process provides a simple and flexible method for probing electronic states and has been one of the most important experimental techniques since the early stages of condensed matter physics. Introducing a magnetic field into transport further generates magnetoresistance and the Hall effect, providing a precise method for assessing carrier concentration and induced magnetic fields, which is widely used in the semiconductor industry. Furthermore, in high-mobility systems, oscillations can be detected in resistivity at low temperatures due to the formation of discrete Landau levels. This allows for the direct measurement of Fermi surface properties such as the Fermi wave vector, quasiparticle effective mass, and quantum lifetime. In recent years, the investigation of quantum oscillations has played a crucial role in the study of two-dimensional electronic systems and topological materials. For transport experiments, different types of excitation lead to different responses in quasiparticle motion. An electrical bias only affects charged carriers and results in movement and momentum displacement across the entire Fermi surface. In contrast, a temperature gradient leads to entropy flow and directional thermal migration of charged and charge-neutral quasiparticles. The ratio of the electronic contribution of electrical conductivity to thermal conductivity can be used to diagnose non-Fermi liquid properties beyond the Wiedemann-Franz law. Therefore, combining multiple transport methods, including electrical, thermal, and thermoelectric conductivity, can help explore different aspects of material properties in a more diverse way.

[0042] Acoustoelectric transport was used to detect the response motion of quasiparticles to external stimuli. Besides the well-known electro- and thermoelectric transport, acoustoelectric transport caused by traveling sound waves has been rarely explored. Therefore, using acoustoelectric transport in extremely low-temperature, high-magnetic-field environments to study the intrinsic properties of materials can add a completely new measurement method to physics research, allowing for the acquisition of more information about the materials' properties. Existing device structures cannot perform angular measurements of material samples in extremely low-temperature, high-magnetic-field environments, resulting in significant limitations in materials research. Compared to existing device structures, the angular measuring device supporting radio frequency transmission proposed in this application can simultaneously introduce radio frequency signals while performing angular measurements of material samples in extremely low-temperature, high-magnetic-field environments. This adjustable-angle acoustoelectric measurement method, as a new detection method, opens up a new measurement dimension for materials research, thereby obtaining more information about the intrinsic physical properties of materials.

[0043] Reference Figure 1-2This application discloses a corner device that supports radio frequency transmission, which can be applied to the study of materials using acoustic-electric transport methods and is suitable for environments with extremely low temperature and strong magnetic fields. It includes a rotating connection mechanism 1, an extension mechanism 2, a sample corner mechanism 3, and a radio frequency connector 4 arranged vertically from top to bottom. When the device is in use, the rotating connection mechanism 1 and the radio frequency connector 4 are located at room temperature, the sample corner mechanism 3 extends into the extremely low temperature and strong magnetic field through the extension mechanism 2, and the radio frequency connector 4 can transmit radio frequency signals to the sample to be tested.

[0044] In this embodiment, the rotating connection mechanism 1 includes a horizontally arranged rotating turntable 11. The rotating turntable 11 can be fixedly connected to the output shaft of the rotating drive component to achieve rotation. The rotating turntable 11 is rotated around its central axis and the rotation axis is arranged in the vertical direction. The radio frequency connector 4 is fixedly installed on the rotating turntable 11 and can rotate synchronously with the rotating turntable 11. The extension mechanism 2 is coaxially fixedly connected to the bottom of the rotating turntable 11. Specifically, the extension mechanism 2 includes several extension sleeves 21. The extension sleeves 21 are connected end to end and are all located on the same axis as the rotation axis of the rotating turntable 11. The uppermost extension sleeve 21 can be fixedly connected to the rotating turntable 11 by bolts. In actual use, the appropriate number of extension sleeves 21 can be used according to the size of the space in the extremely low temperature and strong magnetic field environment so that the sample can be extended to a suitable position for detection.

[0045] Reference Figure 3-5 Specifically, the sample rotation mechanism 3 includes a rotating tray 31, a sample mounting plate 32, and a drive assembly 33 for driving the rotating tray 31 to rotate. It also includes a mounting frame 35 for serving as a mounting carrier. The mounting frame 35 is fixedly connected to the extension mechanism 2, specifically to the lowermost extension sleeve 21 via bolts. The mounting frame 35 has a hollow structure, with both the rotating tray 31 and the sample mounting plate 32 located inside it. The rotating tray 31 is rotatably connected to the bottom end of the extension mechanism 2, specifically, both ends of the rotating tray 31 are rotatably connected to the mounting frame 35. The sample mounting plate 32 is detachably mounted on the rotating tray 31. The rotation axis of the rotating tray 31 forms an angle with the rotation axis of the rotating turntable 11, and the rotation axis of the rotating turntable 11 passes through the middle of the rotation axis of the rotating tray 31. In this embodiment, the rotation axis of the rotating tray 31 is horizontally positioned. In other embodiments, the rotation axis of the rotating tray 31 can be set to an inclined position to increase the rotation dimension of the sample on the sample mounting plate 32.

[0046] More specifically, the sample mounting tray 32 includes two interconnected plates, a first plate 321 and a second plate 322, which are at an angle to each other. The first plate 321 is parallel to and connected to the rotating tray 31 by bolts, thus connecting the sample mounting tray 32 and the rotating tray 31. In this embodiment, the first plate 321 and the second plate 322 are perpendicular to each other. In other feasible embodiments, the second plate 322 can be set to an inclined shape. The sample to be tested is mounted on the second plate 322. The rotating tray 31 is provided with several radio frequency signal interfaces, and the first plate 321 is provided with several corresponding radio frequency signal connectors. The sample mounting tray 32 can be replaced according to actual needs. This device can realize in-plane and out-of-plane rotation of the sample. Furthermore, a damping shaft can be provided between the first plate 321 and the second plate 322. The second plate 322 is rotatably connected to the first plate 321 through the damping shaft, so that the second plate 322 can rotate relative to the first plate 321, thereby driving the sample to move. This allows the installation angle and position of the sample to be adjusted without replacing the sample mounting plate 32.

[0047] Reference Figure 1 and Figure 3 To enable the transmission of radio frequency (RF) signals into the sample under test, a signal transmission component 5 is provided between the RF connector 4 and the rotating tray 31. After the sample mounting plate 32 is installed on the rotating tray 31, the two are electrically connected. When the sample mounting plate 32 and the rotating tray 31 are connected, the RF connector 4 can transmit RF signals into the sample. Specifically, the signal transmission component 5 includes two conductive rods 51 and two connectors 52. The conductive rods 51 are low-loss semi-rigid coaxial lines for RF transmission. The semi-rigid coaxial lines use a robust copper sheath. Compared with the ordinary braided outer conductor, the copper sheath has a better shielding effect, especially at high frequencies. The top ends of both conductive rods 51 are electrically connected to the RF connector 4. Specifically, one conductive rod 51 is connected to the signal output head, and the other conductive rod 51 is connected to the signal input head. Two connectors 52 are electrically connected to the bottom ends of their respective conductive rods 51, and both connectors 52 are fixedly mounted on the mounting bracket 35 with screws. The rotating tray 31 is rotatably connected between the two connectors 52 and electrically connected to them. Furthermore, each extension sleeve 21 is fixedly connected to a heat insulation plate 22. The heat insulation plate 22 has a positioning opening 221 for the conductive rod 51 to pass through, improving the stability of the conductive rod 51 and making it more stable after installation. When the device rotates, the conductive rod 51 can move along with the device during adjustment, avoiding interference during angle adjustment of the corner device and thus affecting the adjustment effect. Simultaneously, the heat insulation plate 22 can act as a baffle, shielding the upper part from heat conduction to the lower low-temperature part, thus acting as a cold shield.

[0048] Reference Figure 5 Furthermore, to drive the rotating tray 31 to rotate, the drive assembly 33 includes a drive motor 331 and a first rotating gear 332. The drive motor 331 is fixedly mounted on the extension mechanism 2, and its output shaft is coaxial with the rotation axis of the rotating disk 11. The drive motor 331 can be directly mounted on the lowest extension sleeve 21, or mounted below the rotating disk 11 and its output shaft extended by an extension rod, depending on its low-temperature resistance. The first rotating gear 332 is fixedly connected to the rotating tray 31 and coaxial with its rotation axis. The drive motor 331 drives the first rotating gear 332 to rotate via a steering assembly 34. The steering assembly 34 includes a rotating rod 341, a second rotating gear 342, a first bevel gear 343, and a second bevel gear 344. The rotating rod 341 is parallel to the rotation axis of the rotating tray 31. Rod 341 is rotatably connected to mounting bracket 35. Second rotating gear 342 is coaxially fixedly connected to rotating rod 341 and meshes with first rotating gear 332. First bevel gear 343 is coaxially fixedly connected to output shaft of drive motor 331. Second bevel gear 344 is coaxially fixedly connected to one side of second rotating gear 342. First bevel gear 343 and second bevel gear 344 mesh. Drive motor 331 can drive first bevel gear 343 to drive second bevel gear 344 to rotate, thereby causing second rotating gear 342 to rotate. After second rotating gear 342 rotates, it can drive first rotating gear 332 to rotate, thereby realizing the adjustment of the angle of rotating tray 31 and sample mounting tray 32. In this structure, the space required for the movement of rotating tray 31 and sample mounting tray 32 is small, which can be used in extremely low temperature and strong magnetic field environments, and the angle adjustment is wider.

[0049] Reference Figure 6 This illustration demonstrates the application scenario of the cornering device disclosed in this application. The shaded area represents an extremely low temperature and strong magnetic field environment. The rotating connection mechanism 1 and the radio frequency connector 4 are located at room temperature. The sample cornering mechanism 3 extends into the extremely low temperature and strong magnetic field via the extension mechanism 2. The radio frequency connector 4 can transmit radio frequency signals to the sample under test. The rotating connection mechanism 1 causes the sample to rotate around a vertical axis, and the sample cornering mechanism 3 causes the sample to rotate around a horizontal axis. While transmitting radio frequency signals, the sample can also be adjusted at multiple angles in the extremely low temperature and strong magnetic field environment, providing new detection methods and new dimensions for scientific research.
