Abstract:
Polarization-sensitive photodetectors, based on anisotropic semiconductors, have exhibited wide advantages in specialized applications, such as astronomy, remote sensing, and polarization-division multiplexing. For the active layer of polarization-sensitive photodetectors, recent researches focus on two-dimensional (2D) organic-inorganic hybrid perovskites, where inorganic slabs and organic spacer
