A portable operation platform for stacking two-dimensional layered heterogeneous materials

Abstract

The invention provides a portable operation platform capable of realizing stacking of two-dimensional layered heterogeneous materials. The portable operation platform is characterized in that when a sample and a glass slide are replaced, a microscope can be removed from a rotary objective stage; when the two-dimensional layered materials are stacked, the angles of sample materials can be adjusted by a track type rotary control platform; when the materials are transferred and stacked, lifting and falling can be realized by the objective stage. The portable operation platform provided by the invention has the advantages that the aligning and calibrating time of the materials is reduced, the working space when the sample materials are arranged is enlarged, the failure of operators due to artificial mistakes is avoided, the stability in material stacking is improved, the flexibility of the experiment is increased, the difficulty of accurate positioning in stacking of the two-dimensional materials is effectively solved, and the application prospect in the aspect of manufacturing the two-dimensional layered heterogeneous materials is good.

Description

technical field [0001] The invention belongs to the field of nanotechnology, and in particular relates to a portable operating platform capable of stacking two-dimensional layered heterogeneous materials. Background technique [0002] With the improvement of the integration level of semiconductor integrated circuits, the size of devices is continuously reduced, and the current mainstream semiconductor transistors have reached a feature size of 22 nanometers. This has reached the top level of existing process technology. However, in recent years, in the field of nanotechnology, there has been an in-depth study of graphene, a layered two-dimensional material. We found that layered 2D materials can break through the technical barriers to electronic device size reduction. Moreover, a variety of layered two-dimensional materials with a structure similar to graphene have also been found to have many excellent properties. If the two are combined to form a new type of semiconducto...

Problems solved by technology

However, the difficulty of preparing 2D layered heterogeneous materials has been hindering the development of this field.

Because in the preparation of two-dimensional layered heterogeneous materials, the size of the materials used is generally only a few to tens of microns, which can only be observed with the help of a high-magnification microscope. The stacking of heterogeneous materials will inevitably involve micro-nano process technology. A slight jitter in the preparation process may affect the performance and contact of the prepared heterogeneous materials, which will directly affect the performance of subsequent heterojunction devices.
