Description

technical field [0001] The invention specifically relates to a microscope and method for compound transfer of perovskite nanowires and black phosphorus films, which are suitable for directional transfer of low-dimensional nanomaterials such as two-dimensional film materials and one-dimensional nanowires, and have multi-functional, high-precision, high-efficiency Technical characteristics such as fault tolerance rate, multi-channel visualization, multi-multiple photo imaging and video recording. Background technique [0002] A microscope is an optical instrument for imaging and characterizing microscopic substances. It is an observation platform that assembles and integrates components such as light source, eyepiece, lens group, objective lens, and stage according to their functions. The microscope combined with the operating platform can observe the microscopic transfer process of materials in real time. [0003] Low-dimensional materials usually refer to nanomaterials with...

AI Technical Summary

Problems solved by technology

[0007] At present, most of the low-dimensional nanomaterial transfer platforms used can only transfer a single material, and the transfer method is single, the compatibility is poor, the microscope magnification cannot be changed, and the observation method of the transfer process is limited (only eyepiece or computer monitor imaging ), can not take pictures, video recording transfer process and other issues

Moreover, some two-dimensional thin film materials are very unstable in the atmosphere, and are easily decomposed under the contact of water and oxygen in the air. Therefore, it is difficult to achieve fixed-point and directional transfer of black phosphorus thin films by conventional transfer methods.
