Description

In recent years emergent two-dimensional (2D) materials such as graphene, h-BN, transition metal dichalcogenides (TMDs), black phosphorous have been hot topics in basic research. However further processing such as patterning, functionalization and integration are often needed for further applications. In this project we will explore efficient approaches to chemically functionalize the 2D van der Waals (vdW) layered materials such as TMDs in parallel with controllable patterning. The unique monoatomic thickness with full surface and various defects such as vacancies, dopants, dislocations and grain boundaries provide bunches of functionalization routes in the TMDs. As one step further, we will combine the patterning strategies like growth control, strain engineering, self-assembly together with the chemical functionalization processes, in the aim of design and fabrication of artificial 2D TMD blocks for specific applications such as integrated electronics, photonic crystals, solar cells, sensors, displays, etc. The main target or deliverable of current project is to accomplish the controllable and tunable patterning in the functionalization processes in 2D materials, understanding the underlying physical/chemical processes, and apply to the products for optoelectronic applications.In recent years emergent two-dimensional (2D) materials such as graphene, h-BN, transition metal dichalcogenides (TMDs), black phosphorous have been hot topics in basic research.
