The Mechanism of 2D Materials Growth and Etching

Deep understanding on the mechanism of growth is essential for the controllable synthesis of high quality 2D materials. In the past, we have paid great effort to explore the mechanism of 2D materials’ growth and etching, and the potential routes towards the controllable synthesis of the desired materials. In this talk, I will present our theoretical study on the kinetics of 2D nanomaterials’ growth and etching, the understanding of various experimental puzzles results and the realization of their controllable synthesis experimentally. The contents will be covered in this talk include: •The mechanism of graphene CVD growth. [1] •The kinetics of 2D materials growth and etching. •The growth mechanism of polycrystalline 2D materials.•Controllable growth of graphene and the strategies toward the quick synthesis of wafer sized single crystal graphene.
