High responsivity photodetector based on monolayer molybdenum disulfide (MoS2)

High-responsivity ultra-sensitive photodetectors are crucial for a broad range of applications in various fields. This work demonstrates a highly sensitive photodetector fabricated by using monolayer molybdenum disulfide (MoS2), a promising semiconductor from the family of transition-metal dichalcogenide, showing a promising photoresponsivity (230 mA/W @532 nm) in the wavelength of visible light region.
