Layered Cs3Bi2I9 perovskite nanosheets on TiO2 nanorods for high performance heterostructure photodetectors

In this study, we report the fabrication of two-dimensional (2D) Cs₃Bi₂I₉ halide perovskite semiconductor photodetectors with enhanced photostability against moisture and temperature. These all-inorganic layered Cs₃Bi₂I₉ nanosheet-based photodetectors exhibit enhanced...
