Abstract:Two-dimensional (2D) semiconductor nanostructures have been emerging as an important class of nanomaterials because of their unique optical and electrical properties and various potential applications in optoelectronic devices and photocatalysts. In this talk, I will introduce our recent research progress on the controlled synthesis of 2D non-layered colloidal semiconductor nanoplates with tailored compositions, from binary to ternary or even quaternary compounds.  Next, some novel heterostructures derived from 2D colloidal nanoplates will be presented, including hierarchical heterostructures with complex architectures, and the heterostructures rationally combined layered and non-layered materials. Finally, the challenge and future directions on the controlled synthesis of heterostructures will be proposed.
