Plasmonic-tape-attached multilayered MoS(2) film for near-infrared photodetection

Molybdenum disulfide has been intensively studied as a promising material for photodetector applications because of its excellent electrical and optical properties. We report a multilayer MoS(2) film attached with a plasmonic tape for near-infrared (NIR) detection. MoS(2) flakes are chemically exfol...

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