研究领域

Our research group is interested in synthesis, crystal structure determination, electronic structure calculations and physical properties measurement of some functional materials. The major focus is devoted to the energy related functional Materials (Thermoelectrics, Hydrogen Production Photo-catalysts, Fuel Cells), and exotic magnetic properties in extended solids. A good understanding of the connections between crystal structure, electronic structure and physical properties will lead us to rationally design and produce these functional materials. The crystal structure (elemental composition, bonding characteristics and connectivity) determines the electronic structure, which in turn explains the physical properties.
