LIU Chang - The Department of Physics at Southern University of Science and Technology

Personal Profile

LIU Chang, Professor of the Department of Physics, SUSTech. Dr. Liu’s research mainly focuses on revealing the novel electronic properties of functional materials such as magnetic, topological, and thermoelectric materials, using angle resolved photoemission spectroscopy (ARPES) and other spectroscopic techniques. His research group also masters the techniques of material growth such as the flux method, chemical vapor transfer (CVT) and molecular beam epitaxy (MBE). On the field of magnetic materials, his work uncovers the spin splitting of energy bands in an unconventional antiferromagnet. In the field of topological materials, his works presented e.g., a gapless topological surface state in magnetic topological insulators and the Fermi arcs in three dimensional Dirac semimetals.
