General Research Interests
My research interests focus on studying electronic and structural properties of semiconductor materials with special emphasis on new materials for energy conversion and conservation.  The research is performed in the Solar Materials Research Group, a team of 15 researchers, post-docs and graduate students working on materials synthesis, materials characterization and device design.  The group has extensive collaborations with scientists from LBNL, UC Berkeley and from other universities and national laboratories.  The main areas of interest include group III-nitrides and recently discovered highly mismatched alloys.  The research on nitride semiconductors concentrates on applications of these materials for multijunction solar cells and photoelectrochemical cells for solar water splitting.  The studies of highly mismatched alloys focus on synthesis of new materials with the electronic structure suitable for intermediate band and hot electron solar cells.
