Assistant Professor Department of Physics

I graduated in University of Science and Technology of China (BSc) and Hong Kong University of Science and Technology (PhD), in 2006 and 2011, respectively. In 2012, I joined SUSTech, as an assistant professor in Dept. of Physics. My research lies in the experimental Condensed Matter Physics. Using Molecular Beam Epitaxy, my research team pays utmost effort on realizing wafer-size low dimensional quantum system composed of semiconductor/superconductor, semiconductor/magnetism hetero-structures. Different with tranditional thin film systems, strong orbital coupling (SOC) is integrated into the system by adding heavy atoms such as Bismuth or Tellurium, aiming to study topological physics in the two-dimensional scale. The major characterizations we used are Transmission Electron Microscopy, Scanning Tunneling Microscopy together with Ultra-violet Photoelectric Spectroscopy techniques.
