快速响应宽光谱二维SnSe光电探测器
Fast-speed response wide spectrum two-dimensional SnSe photodetectors
摘要
Abstract
Infrared photodetectors have important applications in thermal imaging,optical communications,and night vision cameras.However,the current fabricated infrared photodetectors generally suffer the problems of low-temperature operation and slow response speed.To address those problems,this paper proposed to use the SnSe to fabricate a photodetector.The performance of the SnSe photodetector was systematically investigated.The detector has high photoresponsivity and ultra-fast optical response time under visible light irradiation with a wavelength of 637 nm,and the photoresponsivity of the detector under infrared laser irradiation with a wavelength of 3 250 nm can reach 35 mA·W-1,showing excellent infrared detection capability.关键词
