The AgNCs decorated MoS2 film shows 19-fold increment in photocurrent compared with pristine MoS2 film.

The photoresponsivity of MoS2 with AgNCs-based flexible photodetector increased 38 times to 7940 A W−1 at 3 V under 2.2 pW incident power compared with pristine MoS2 film with decreasing incident power intensity due to the reduced scattering and recombination of the photogenerated charge carriers. Photocurrent rise time (τrise) of 0.3 s and decay time (τdecay) of 1.6 s were estimated for the flexible MoS2/AgNCs hybrid-based photodetector. The flexible photodetector showed good mechanical stability after bending at a curvature of 8 mm 10 000 times because a 71% photocurrent ratio of devices was retained. The photocurrent initially decreased up to 3000 bending cycles, but no noticeable decrease in photocurrent ratio was observed thereafter. These studies show that integrating plasmonic nanostructures with MoS2 atomic layers can significantly increase the photoresponsivity of MoS2-based photodetectors—schematic diagram of the 1L-MoS2 and Ag nanowires (NWs) based photodetector. The upper area shows the schematic diagrams of the pristine 1L-MoS2 and the 1L-MoS2/AgNWs hybrid photodetector on a glass substrate along with Cr/Au electrodes.
