LIU Chang, Associate Professor at the Department of Physics, SUSTech. Dr. Liu's research mainly focuses on revealing the novel electronic properties of functional materials such as magnetic materials, topological materials, thermoelectric materials, etc., 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 and an exotic surface state in three dimensional Dirac semimetals. On the field of thermoelectric materials, his works revealed the valence band information on a series of SnSe-based high-performance thermoelectric compounds.
