Brief Introduction
LIU, Chang, Associate Professor at the Department of Physics, SUSTech. Dr. Liu's research mainly focuses on revealing the novel electronic properties of topologically non-trivial materials, thermoelectric materials and high temperature superconductors; as well as the exotic electronic behavior in graphene and related structures, using angle resolved photoemission spectroscopy (ARPES), scanning tunneling microscopy (STM) and other spectroscopic techniques. His research group also masters the techniques of material growth such as the flux method, chamical vapor transfer (CVT) and molecular beam epitaxy (MBE). On the field of topologically non-trivial materials, his works presented e.g. a gapless topological surface state in magnetic topological insulators, an exotic surface state in three dimensional Dirac semimetals, and the first example of topological crystalline insulator (TCI). On the field of thermoelectric materials, his works revealed the valence band information on a series of SnSe-based high-performance thermoelectric compounds.
