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.
