The halide perovskites AMX3 (A = large cation, B = Sn or Pb, and X = halide) have been the subject of intense investigation due to their outstanding optical and electronic properties, which have enabled high solar cell efficiencies thanks to a beneficial electronic structure and long charge carrier lifetimes....
The important application for the infrared photodetectors is mainly thermal imaging by focal plane arrays (FPAs) for military and commercial purposes. So far, most mid-wavelength infrared (MWIR) and long-wavelength infrared (LWIR) FPAs are based either on HgCdTe (MCT) or quantum well infrared photodetectors (QWIPs). Even though those technologies are well...
