Within the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Strength donors, are photoexcited to an thrilled point out, they could transfer their Power non-radiatively to Bi2O2Se through dipole–dipole interactions. This leads to electrons during the valence band of Bi2O2Se to transition on the conduction band. While in https://www.youtube.com/@%E0%B9%84%E0%B8%A7%E0%B8%88%E0%B8%A3%E0%B8%B4%E0%B8%87
