About Dr. Tan’s Research Group

Our group focuses on the discovery of functional and multifunctional inorganic solid-state materials, ranging from intermetallics to oxides, with applications in technology and energy conversion. We specifically target materials with noncentrosymmetric and polar space groups, which include (but not limited to) metallic oxides, oxide thermoelectric materials, multiferroics, and magnetic semiconductors.

Students will be trained on the synthesis of crystalline inorganic solid-state materials by various methods, growth of single crystals, structural analysis, calculations of the electronic structure, and characterization of the physical properties of inorganic solid-state materials. Students will also have the opportunity to learn X-ray neutron diffraction while using state-of-the-art research facilities at national laboratories such as Argonne National Laboratory (ANL), Brookhaven National Laboratory (BNL), National Institute of Standards and Technology (NIST), and Oak Ridge National laboratory (ORNL).
