文摘

The effects of triphenylphosphine and (3-aminopropyl)triethoxysilane on a rhenium diselenide (ReSe₂) photodetector are systematically studied by comparing with conventional MoS₂ devices. This study demonstrates a very high performance ReSe₂ photodetector with high photoresponsivity (1.18 × 10⁶ A W⁻¹), fast photoswitching speed (rising/decaying time: 58/263 ms), and broad photodetection range (possible above 1064 nm).
