I started my academic career as a physicist by training. I went to Wuhan University in October 1978 to read a four year BSc degree course in Semiconductor Physics. This was followed by a three year MSc degree course in Solid State Physics from September 1982 to August 1985.
From September 1985, I became a junior staff member working in Physics Department at Wuhan University, first as demonstrator and then promoted to junior lecturer position two years later. My research interest at Wuhan University was on the electronic structures and optical properties of layered 3d transition metal intercalated transition metal dichalcogenide crystals.
In 1988, I was awarded a Bank of Credit and Commerce International (BCCI) scholarship and Overseas Research Scholarship (ORS) for my PhD study in Physics and Chemistry of Solids (PCS) Group at Cavendish Laboratory, Cambridge University.
My PhD thesis was on isomorphic site selective substitution in high temperature superconducting YBa2Cu3O7-δ. I moved to School of Chemistry at Leeds University in January 1992 to work on high pressure and high temperature solid state synthesis of novel perovskite oxides such as CaFeO3-δ, then to School of Chemistry at St Andrews in March 1995 to work on SrNbO3-δ.
I joined Surrey Ion Beam Centre from January 1998, first on the fabrication of high temperature superconductor Josephson junctions using masked ion beam irradiation, later as a Liaison Fellow working with a number of research projects supported by EPSRC and other funding agencies.
In a few words, my research interest is mainly on the experimental manipulation of physical properties of novel solid state materials under extreme physical conditions such as temperature, pressure and ion beam irradiation/implantation etc. Typical examples include:
- Introduction of point defects in establishing magnetic ordering in conventional semiconducting materials, in suppressing superconductivity and in studying robust structural materials
- Manipulation oxygen nonstoichiometry in perovskite oxides on magnetic ordering and lattice distortion
- Ion beam synthesis of novel materials.
