英文摘要: Inorganic semiconductor nanomaterials have tremendous potential applications in sensors, field-emmision devices and solar cells. Sizes, controllable morphology nanomaterials and its electronic/optoelectric devices are one of promising research fields. Control and regulate namometerials dimensional, size and morphorlages can significantly improve the optoelectric properties of the devices such as detectivity of photodetectors and energy conversion efficiency of solar cells. In order to explore new semiconductor nanostructures for high-performance optoelectric devices, in this project, we aim to fabricate multi-dimensional oxide/sulfide semiconductors via hydrothermal self-assembly and Schlenk line techniques methods, as well as the growth mechanism, optoelectric and solar cells performance. These studies are very useful and helpful for developing nanomaterials-based photodetectors and solar cells.
