Title:
TWO-DIMENSIONAL TELLURIUM NANOSHEET, MANUFACTURING METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/153699
Kind Code:
A1
Abstract:
The present invention provides a two-dimensional tellurium nanosheet. The two-dimensional tellurium nanosheet has a thickness of 1-50 nm. The two-dimensional tellurium nanosheet provided by the present invention has excellent photoelectric detection performance. The present invention further provides a manufacturing method for the two-dimensional tellurium nanosheet, comprising the following steps: providing a tellurium raw material, and exfoliating the tellurium raw material by means of liquid phase exfoliation to obtain a two-dimensional tellurium nanosheet, the two-dimensional tellurium nanosheet having a thickness of 1-50 nm. According to the present invention, a two-dimensional tellurium nanosheet is manufactured from a non-layered tellurium raw material by means of liquid phase exfoliation for the first time, and the exfoliation effect is good; moreover, large-scale manufacturing of two-dimensional tellurium nanosheets can be implemented, the costs are low, and the manufacturing method is simple and easy to operate. The present invention also provides an application of the two-dimensional tellurium nanosheet in a photodetector.
