Abstract

New CW THz detectors based on graphene nanoelectrodes photomixer are completely investigated. The graphene nanoelectrodes are placed on low-temperature-grown (LTG) GaAs as photoconductive material. Due to the high transparency and high conductivity of graphene, increasing carrier densities were obtained which leads to the high performance detection of THz induced photocurrent being one order of magnitude higher than for conventional metallic interdigitated photomixer. The THz measurement was performed in the range of 50 GHz to 1.1 THz.
高性能石墨烯基连续波太赫兹光导探测器
研究了基于石墨烯纳米电极的新型连续波太赫兹探测器。石墨烯纳米电极作为光导材料放置在低温生长(LTG) GaAs上。由于石墨烯的高透明度和高导电性,增加了载流子密度,从而使太赫兹感应光电流的高性能检测比传统的金属交叉式光电混合器高一个数量级。太赫兹测量在50 GHz到1.1太赫兹范围内进行。
