Kin Man Yu received his Ph. D. in Materials Science and Mineral
Engineering at UC Berkeley in 1987 and is a LBNL staff scientist and a principal
investigator in the Electronic Materials Program, Materials Sciences Division. Dr. Yu’s research interests include the
following areas:
• Design, synthesize and
characterize novel highly mismatched III-V and II-V semiconductor alloys for photovoltaic
applications
• Structural, optical
and electrical properties of group III nitrides for full spectrum PV
applications
• Ion beam analysis and modifications
of semiconductors
• Defects in
semiconductors
Dr. Yu holds several patents related to new materials for PV
applications and has published over 400 articles in refereed journals and
conference proceedings with over 9500 total citations and a h-index of 46. He also co-authored 11 invited reviews
and book chapters. Together with
Dr. W. Walukiewicz, Dr. Yu received the 2006 R&D 100 award (Editor’s
choice) for “most promising technology” for their invention on “multiband
semiconductor for high efficiency solar cell."
