The fabricated MoS2 phototransistor and electrical characteristics. a Schematic diagram of the fabricated multi-layer MoS2 phototransistor. b Atomic Force Microscope (AFM) image of the phototransistor. The inset is the cross-section plot along the red line in the AFM image. c Transfer characteristics of the multi-layer MoS2 phototransistor with the drain voltages of 3, 9, 15, 21, and 27 V in the dark. d Variations in the subthreshold swing with increasing drain bias
