Abstract

Since the graphene was found

with the continuous research and exploration by people

more and more two-dimensional materials with similar structures have been discovered and studied successively due to their excellent photoelectrical properties. The widespread attention is paid to the transition metal dichaldogenides(TMDs) due to their rich physical properties. This paper researches the two-dimensional three-layer WSe

photoelectric property

and transfers it to the Au electrode of SiO

/Si substrate by Van Der Waals force. Finally

the silver paste is used to extract the back gate electrode with WSe

field effect transistor manufactured

whose carrier mobility is 3.42 cm

/(V·s). The detector response ratio of the WSe

field effect transistor based on the 630 nm wavelength is 0.61 A/W and the light response recovery time is 1 900 ms.
