The effects of triphenylphosphine and (3‐aminopropyl)triethoxysilane on a rhenium diselenide (ReSe 2 ) photodetector are systematically studied by comparing with conventional MoS 2 devices. This study demonstrates a very high performance ReSe 2 photodetector with high photoresponsivity (1.18 × 10 6 A W −1 ), fast photoswitching speed (rising/decaying time: 58/263 ms), and broad photodetection range (possible above 1064 nm).
