Problems solved by technology

This method is relatively complicated to operate, but it can be applied to the fixed-point transfer of a single-layer two-dimensional material with a micron-scale size
However, during the transfer process, since the polymer layer is not smooth enough, there is no way to effectively contact the polymer layer during the first adhesion without affecting the precise operation under the microscope, so the dry fixed-point printing method Transfer failure rate is high

Embodiment

[0016] Transfer single-layer graphene on a silicon substrate to a single-layer molybdenum diselenide on a silicon substrate:

[0017] 1. Put the PDMS in the middle of the through hole 2 of the device, take the PC film to cover the PDMS and stick it on the curved glass 1.

[0018] 2. Fix the silicon substrate with single-layer graphene on the heater, raise the temperature of the heater to 80°C, adjust the focus under the microscope, and find the graphene to take pictures.

[0019] 3. Fix the device on the four-dimensional translation platform through the fixed handle 3, and press the PC film attached to the through hole 2 of the device on the found single-layer graphene by adjusting the position and angle of the translation platform .

[0020] 4. Raise the temperature of the heater to 120°C and lift up the device. Observe whether the graphene on the silicon wafer is still there, if still repeat step 3. If it is not there, it means that the graphene has stuck to the PC film a...

Abstract

The invention discloses a device for fixed-point transferring of a single-layer two-dimensional material. Traditional flat glass is replaced with curved glass with a rectangular through hole in the middle; an anti-skid fixed handle with sawteeth is added to one end of the curved glass; and the middle hole in the curved glass is used for dipping the single-layer two-dimensional material. A polymer layer thin film is flat and is in effective contact with the single-layer two-dimensional material without a buffer, so that the fixed-point transferring of the single-layer two-dimensional material is achieved.

Description

technical field [0001] The invention relates to the operation of a single-layer two-dimensional material with a micron-scale size, and in particular to a device for transferring a single-layer two-dimensional material mechanically peeled off with a micron-scale size. The device was designed for the transfer of single-layer 2D materials. Background technique [0002] Two-dimensional materials include graphene, black phosphorus, molybdenum disulfide, molybdenum diselenide, tungsten disulfide, BN, etc. They have attracted extensive attention in the industry due to their unique spatial structure and electrical and thermal properties. At present, the main preparation methods of single-layer two-dimensional materials are: mechanical exfoliation method, chemical exfoliation method, chemical vapor deposition (CVD) method, etc. Although the growth of single-layer two-dimensional materials by CVD has made great breakthroughs in recent years and is a very promising synthesis method, ...
