基于碲纳米线光热电效应的室温高灵敏太赫兹探测器
Room-temperature highly sensitive terahertz detector based on the photothermoelectric effect of Te nanowires
摘要
Abstract
Highly sensitive detectors operating at room temperature are the core devices urgently needed to realize the wide application of terahertz technology.In this paper,a room-temperature terahertz detector based on the photothermoelectric effect is developed.Using tellurium(Te)nanowires as the channel material,and tilted-angle evaporation method is employed to fabricate the channel with a length of less than one hundred nanometers,and the Te nanowires are doped by asymmetric metal to give asymmetric thermoelectric properties at both ends.Experimental results demonstrate that the device can achieve a responsivity of 54.63 V/W under 0.288 THz illumination,with a Noise Equivalent Power(NEP)of 33.5 pW/Hz1/2,and a response time of 71.1 μs,which realizes a highly sensitive and rapid terahertz detection under room temperature conditions.关键词
