Within the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Strength donors, are photoexcited to an fired up state, they might transfer their Electrical power non-radiatively to Bi2O2Se by dipole–dipole interactions. This brings about electrons within the valence band of Bi2O2Se to changeover for the conduction band. In https://waiijing98753.theideasblog.com/28707675/the-ultimate-guide-to-waiijing
