摘要：Since the first isolation of graphene from graphite by mechanical exfoliation, atomically-thin or layered materials have been occupying the central stage of today’s condensed matter physics and materials sciences because of their rich and exotic properties in two dimensions (2D). Many members of the ever-expanding 2D materials family share the distinct commonality of possessing relatively-weak van der Waals (vdW) interlayer coupling, whereas each member may invoke its own fabrication approaches, and is characterized by its unique properties. In this presentation, we first discuss the major atomistic processes and related morphological evolution in the epitaxial growth of graphene, such as nucleation, diffusion, feedstock dissociation, and grain boundaries, and further review the current status of the vdW epitaxy of newly discovered 2D materials. We also briefly highlight on some of our recent advances in the property optimization and functionalization of 2D materials as well as search for new 2D members.
个人简介：Dr. Jin-Ho Choi earned his PhD from Hanyang University (Korea) in 2011. He then worked as a distinguished postdoctoral researcher at the International Center for Quantum Design of Functional Materials (ICQD), University of Science and Technology of China between 2011 to 2015. During 2015 to 2016, he has been a research professor fellow at Department of Energy and Materials Engineering and Advanced Energy and Electronic Materials Research Center, Dongguk University. He is currently a researcher fellow at Research Institute of Mechanical Technology, Pusan National University. So far, Dr. Jin-Ho Choi has published more than 26 papers. His research interests lie particularly on the following aspects: 1) Discovery and optimization of new advanced materials based on theoretical search methods;2) Interfaces in thin film solar cells and related heterostructural materials for clean energy;3) Stability and performance of photovoltaic devices;4) Excitonic properties of low-dimensional materials;5) Graphene synthesis on metal substrate;6) Self-assembly of low-dimensional nanostructures on solid substrates;7) Quantum effects in low-dimensional nanostructure.
