Synthesis of High-Quality 2D Materials for Electronic Applications

The development of graphene research has opened a new field of atomically thin, two-dimensional (2D) layered materials. They have unique properties, such as high carrier mobility, mechanical flexibility, optical transparency, high thermal conductivity, and high degree of freedom of staking angles. These properties stimulate the research on the applications of 2D materials to electronic and photonic devices. However, for realizing such applications, it is very important to synthesize large-area 2D materials with high crystallinity and low defect density. In this presentation, our recent progress of the chemical vapor deposition (CVD) growth of graphene, transition metal dichalcogenides (TMDCs), and hexagonal boron nitride (h-BN) is presented with the emphasis on our original epitaxial growth approach for high-quality films. Moreover, I will also demonstrate our recent work on new types of 2D heterostructures.
