In this study, a near-infrared photodetector featuring a high photoresponsivity and a short photoresponse time is demonstrated, which is fabricated on rhenium diselenide (ReSe2) with a relatively narrow bandgap (0.9-1.0 eV) compared to conventional transition-metal dichalcogenides (TMDs). The excell...
