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.

The Department of Physics at Southern University of Science and Technology has been established since 2011. The Department’s commitment is to develop first-class education and top-notch research in physics. The Department of Physics has been granted authority to award bachelor's degree in Physics and Applied Physics. Moreover, the Department offers long-term joint Master and PhD programmes, in collaboration with other renowned universities, including Peking University, Harbin Institute of Technology, University of Hong Kong, Hong Kong University of Science and Technology, and National University of Singapore. In addition, the Department has established long-term joint post-doctoral workstations with Peking University, Fudan University, Wuhan University and other colleges and universities.
The Department has a current size of 38 academic staff, including 7 chair Professors, 4 Professors, 20 Associate Professors, and 7 Assistant Professors. There are 4 Academicians of the Chinese Academy of Sciences (including joint employment), 5 Distinguished Young Scholar, and 5 “Pengcheng” scholars. All members of our academic staff have study or work experience at top 100 universities in the world.
