Abstract

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 × 10(6) A W(-1) ), fast photoswitching speed (rising/decaying time: 58/263 ms), and broad photodetection range (possible above 1064 nm).

摘要

通过与传统的 MoS2 器件进行比较,系统地研究了三苯基膦和(3-氨丙基)三乙氧基硅烷对二硒化铼(ReSe2)光探测器的影响。本研究展示了一种具有高光响应率(1.18×10^6 A W^-1)、快速光开关速度(上升/下降时间:58/263 ms)和宽光探测范围(可能超过 1064 nm)的高性能 ReSe2 光探测器。
