Abstract

Metal–semiconductor–metal (MSM) photodetectors offer efficient solutions for many applications. Here, we combine surface energy assisted wet transfer of a MoS2 monolayer with patterned interdigitated platinum electrodes. The chemical vapor deposition (CVD)-deposited MoS2 monolayer is analyzed for various performance parameters. The achieved dark current and photocurrent are 5.37 × 10–8 A and on the order of 10–5 A, respectively. The achieved peak responsivity and peak external quantum efficiency are 13.15 mA/W at 480 nm and 21.86% at 4.5 V, respectively. The Ion/Ioff ratio obtained is 256 for 5 V with a rise and fall time of 0.06 and 0.14 ms, respectively.
