Plasmonic enhancement of photocurrent in MoS2 field-effect-transistor

摘要

The two-dimensional material, molybdenum disulfide (MoS2), has attracted considerable attention for numerous applications in optoelectronics. Here, we demonstrate a plasmonic enhancement of photocurrent in MoS2 field-effect-transistor decorated with gold nanoparticles, with significantly enhanced photocurrent peaked at the plasmon resonant wavelength around 540?nm. Our findings offer a possibility to realize wavelength selectable photodetection in MoS2 based phototransistors.
