From: Bias-dependent photoresponsivity of multi-layer MoS2 phototransistors
Photoresponse characteristics measured at four different irradiances (5, 7, 8, and 10 mW/cm2) when the drain bias is increased. a Photocurrent, b responsivity, and specific detectivity in the OFF state. Insets in a and b are plotted with the log scale of the photocurrent and responsivity, respectively. c Photocurrent, d responsivity, and specific detectivity in the ON state
