| titleOfInvention | A kind of high-performance photodetector and preparation method thereof |
| abstract | The invention belongs to the technical field of photodetectors, and discloses a method for preparing a high-performance photodetector, in which CdS x Se 1-x nanosheets are spin-coated on a silicon-based substrate, and electron beam lithography and electron beam evaporation coating technologies are used A gold electrode is deposited, then CsPbBr 3 nanocrystals are spin-coated, and after annealing treatment, a composite structure photodetector of all-inorganic CsPbBr 3 perovskite nanocrystals/two-dimensional non-layered cadmium selenium sulfide nanosheets is obtained. The invention utilizes the high stability of the all-inorganic perovskite crystal, and combines the excellent physical properties of the two-dimensional non-layered material with the strong light absorption characteristics of the perovskite to improve the charge loading at the interface of the composite nanostructure. carrier transport capability, thereby improving the performance of photodetectors. |
