Inspired by the unique, thickness-dependent energy band structure of 2D materials, we study the electronic and optical properties of the photodetector based on the as-exfoliated lateral multilayer/monolayer MoS<sub>2</sub> heterojunction. Good gate-tunable current-rectifying characteristics are observed with a rectification ratio of 10<sup>3</sup> at V <sub>gs</sub> = 10 V, which may offer an evidence on the existence of the heterojunction. Upon illumination from ultraviolet to visible light, th ...[more]
