Two-dimensional Materials: Structures, Defects and Functionalities

Program Description

Following the discovery of graphene, over hundreds of two dimensional (2D) materials have been found in last decade. 2D materials often show unusual characteristics in structure and properties, such as exotic topological states and catalytic activities, and are emerging as a new class of structural and functional materials. Similar to their bulk counterparts, 2D crystals also have rich in-plane and out-of-plane structures which are comprised of various geometric, topological and chemical defects. These defects contribute to and even control the properties of the 2D materials. Along this line, in the talk I will briefly introduce our recent work on synthesis and characterization of 2D transition metal dichalcogenides (TMDs) graphene. By designing, manipulating and constructing the structures and 3D architectures of monolayer TMDs and graphene, new functionalities of the 2D crystals can be created for applications in electronics, optics and energy storage and conversion.
