I started my condensed matter physics course from Lanzhou (B.S.) and Nanjing (M.S.) Universities in China. Later I moved to Germany and earned a Ph.D. in physics from Leibniz IFW-Dresden/TU-Dresden in Oct. 2003. My work was focused on  spectroscopic studies of electronic properties of carbon nanotubes/fullerene with wide ranges of spectroscopic techniques, e.g., photoemission in lab and synchrotron sources, electron energy-loss spectroscopy, optics, Raman, and so on. In 2004, I entered the field of the organic interface with lab and synchrotron based photoemission and adsorption.

 After that, I spent several years in Austria and US to continue and enlarge my research interest with other spectroscopic techniques, such as scanning probe microscopy/spectroscopy. Most topics were related to study the  electronic and optical properties of nanocarbon (nanotubes/nanodiamond) and organic molecules. In 2011, I joined the surface physics and chemistry group.


1. Surface physics analysis and spectroscopic techniques.

2. Electronic and structural properties of organic molecules on metal surfaces

3. Interface engineering in organic electronics.

4. Application of nanocarbon materials (fullerence, graphene, nanotubes) on organic electronics

    and their intrinsic interface properties

5. Synthesis and characterization of nanocarbon materials and their derivatives.
