I mainly focus on understanding and solving a series of fundamental physics related to luminescence in wide-bandgap semiconductors, low-dimensional semiconductors by quantum-mechanical calculations. By revealing the process of excitation and energy conversion in condensed matter, we can effectively optimize the properties of the advanced optoelectronic materials for the urgent applications in the future. My research includes:

1) Characterization and control of defect/doping physics in wide-bandgap oxide semiconductors.

2) Computational study on the atomic structure and electronic/optoelectronic properties of low-dimensional semiconductors.

3) Simulation on the dynamic process of excited-state carriers in semiconductor materials.
