NOVELTY - The utility model belongs to the field of photoelectric detector, specifically is a method of using gold particle spin coating the MoS2/ graphene heterojunction surface obtained with enhanced plasma MoS2/ graphene photodetector, comprising a gate electrode, a ferroelectric insulating layer, using gold particles coated on the MoS2/ graphene heterojunction surface to obtain MoS2/ graphene vertical heterojunction with enhanced plasma, Pt source electrode and Pt electrode. strong selective light-absorbing MoS2 layer in this utility model generates a charge, the charge transferred to the graphene by the built-in electric field, and because the high carrier mobility of graphene, charge can be recycled for many times to the graphene layer. and the graphene MoS2/ on the vertical heterojunction light field of spin coating with gold particles can be generated by the surface plasma exciting enhancement of effectively increasing the local electric field intensity, improve the photoelectric conversion efficiency, increase the photocurrent. incident light is absorbed can be effectively transformed into surface plasmon, enhance absorption of the incident light.
