Claim 0:
1. A visible light detector with photoresponse based on a TiO2/MoS2 heterojunction, comprising a MoS2 channel, a TiO2 modification layer, a SiO2 dielectric layer, Au source/drain electrodes and a Si gate electrode, the TiO2 modification layer being modified on the surface of the MoS2 channel, the TiO2 modification layer being obtained from e-beam evaporation of a certain thickness of metallic Ti film on the surface of the MoS2 channel and natural oxidation of the metallic Ti film, and the MoS2 channel being a few layers of MoS2 flakes with a crystallinity.
