A two-dimensional channel structure and its preparation method

Abstract

The invention discloses a two-dimensional channel structure and a manufacture method thereof. A support is used for supporting separation layers to obtain multiple kinds of two-dimensional channel structures. The range of applicable materials is broad. The spacing distance of all layers is precise and controllable. Constraints on design of the two-dimensional channel structure are few so that a great number of patterns are suitable for the two-dimensional channel structure. The two-dimensional channel structure is suitable for industrialized production, with high-precision images being produced. As a result, the two-dimensional channel structure is suitable for multiple kinds of industrial production methods. The manufacture method is easy and low in cost and extensive in applications. Due to few technological constraints, the two-dimensional channel structure is suitable for multiple techniques. Circuits can be designed on the separation layers. Through an external power supply or an electric signal or a light source or modulation of different entrance pressure intensities, ion or molecule directions can be controlled so that purposes of energy conversion or drug synthesis are fulfilled. The patterns are combined with proper detection means (such as Raman spectroscopy, fluorescence spectra and the like) so that single molecules can be effectively detected or other biological detection and chemical detection can be carried out. The patterns can be combined with a large number of systems.

Description

technical field [0001] The invention relates to semiconductor preparation technology, in particular to a two-dimensional channel structure and a preparation method thereof. Background technique [0002] Two-dimensional materials such as graphene, transition metal chalcogenides (such as MoS 2 etc.) and the III-V quantum well structure can effectively confine the electrons in it and thus have many applications. The analogy to the hollow two-dimensional structure can form a good confinement of ions, electrolytes, organic molecules, etc., and can effectively control their transport. At the same time, the hollow two-dimensional layered structure has a large surface area and can be used for various applications such as gas adsorption, particle adsorption, chemical synthesis, batteries, and capacitors. Most of the two-dimensional layered structures today are prepared by using two-dimensional layered materials as the isolation layer, and the stripping-reconstruction method is adop...

AI Technical Summary

Problems solved by technology

[0003] Due to the limitations of materials and preparation processes, the exfoliation-reconstruction method is only suitable for natural layered materials, and the spacing between layers is difficult to fine-tune, even if chemical surface modification is used.

Although the capillary-tight compression method can effectively control the average spacing of two-dimensional channels, the fluctuation deviation is large, and it is impossible to accurately study the influence of different interlayer spacings in a single two-dimensional channel on ion transport, electrolyte, gas transport, etc. , and only natural layered materials can be used

At the same time, it is difficult to finely control the surface charge density of natural layered materials by doping and other methods. The surface charge density control of existing methods can only be completed through subsequent surface processing, and it is difficult to achieve positive surface charge.
