Qixi Mi

Prof. Mi earned his B.S. degree from Peking University in applied chemistry (2003) and his Ph.D. degree from Northwestern University in chemistry (2009). Later he performed postdoctoral research at California Institute of Technology, taking advantage of a fellowship of the NSF Center for Chemical Innovation (CCI Solar), and then briefly at the Argonne–Northwestern Solar Energy Research (ANSER) Center.                                 

Physics and chemistry of materials; Renewable energy.

The research projects in Mi group include: novel halide semiconductor materials, conversion and utilization of solar energy, solar water splitting for hydrogen generation, photoelectrochemistry, and time-resolved optical/magnetic spectroscopies. The research methods cover theoretical calculations, materials synthesis, device fabrication, as well as measurements and characterizations, enabled by a complete set of research tools.
