随着红外技术的发展，未来红外探测器向着mK或亚mK灵敏度红外探测系统方面发展，传统探测器已经很难满足需求，光电探测器的响应度亟待提高。主要基于石墨烯材料的独特能带结构、超高载流子迁移率、超宽光谱吸收的特性，结合碲镉汞光电探测材料的极高量子效率性能，研究了具有极高红外辐射响应度、超宽光谱响应范围的新一代石墨烯基复合红外探测材料。

With the development of infrared technology, infrared detectors will develop toward mK or sub-mK sensitivity infrared detection systems in the future. Since traditional detectors are difficult to meet these development requirements, the responsivity of photoelectric detectors needs to be improved urgently. On the basis of the unique energy band structure, ultra-high carrier mobility and ultra-wide spectral absorption characteristics of graphene materials, a new generation of graphene-based composite infrared detection materials with extremely high infrared radiation responsivity and ultra-wide spectral response range are studied in combination with the extremely high quantum efficiency of HgCdTe photoelectric detection materials.
