In this work, large crystal atomic layer PtSe2 with a narrow band gap is synthesized by chemical transfer method. We then demonstrated, for the first time, mid-infrared photodetectors based on bilayer PtSe2 with fast response time and high responsivity up to 4.5 A/W under mid-infrared illumination (...
