Abstract Molybdenum disulfide has been intensively studied as a promising material for photodetector applications because of its excellent electrical and optical properties. We report multilayer MoS 2 film attached with plasmonic tape near-infrared (NIR) detection. flakes are chemically exfoliated transferred onto polymer substrate, silver nanoparticles (AgNPs) dewetted thermally on substrate Scotch tape. The AgNPs is directly simply the flakes. Consequently, NIR photoresponse device critically enhanced. proposed transfer method enables formation structures arbitrary substrates, such without requiring high-temperature process. performance AgNPs-MoS photodetectors approximately four times higher than that bare devices.
