Experience

Wenjun Zhang studied physics and materials science at Lanzhou University, PR China. (B.Sc. 1988, M. Sc. 1991, Ph.D. 1994).  He was a post doc at the Fraunhofer institute for Surface Engineering and Thin Films (FhG-IST) in Braunschweig, Germany, from 1995 till 1997. He became a research fellow in City University Hong Kong from 1997 till 1998, then spent two years in National Institute for Research in Inorganic Materials (NIRIM), Japan as a Science and Technology Agency (STA) Fellow. In December 2000 he joined City University Hong Kong again as a senior research fellow. He is now a Professor in the Department of Physics and Materials Scienec, and he is also the deputy director of the Center Of Super Diamond and Advanced Films (COSDAF).

 

Research Interests

Thin film technology, Diamond and superhard materials, Surface and interface analysis, Nanomaterials and nanodevices.
