Wladek Walukiewicz graduated from Warsaw University in 1971 with an M.S. in
Physics and from the Institute of Physics Polish Academy of Sciences in 1974
with a PhD in Solid State Physics. From 1974 to 1982 he worked for the Institute
of Physics. During that time he was a frequent visitor at the Massachusetts
Institute of Technology where he conducted studies on electrical and optical
properties of compound semiconductors. In 1984 Dr. Walukiewicz joined Lawrence
Berkeley Laboratory as a staff scientist. He currently holds a position of
senior staff scientist, principal investigator in the Materials Sciences
Division, and deputy Program Leader of the Electronics Materials Program. Dr.
Walukiewicz’s work covers a broad range of topics in the physics of semiconductors.
He has developed models of electronic transport in three- and two-dimensional
systems. He has made major contributions to understanding the defect properties
of semiconductors. Working with a group of collaborators Dr. Walukiewicz has
discovered highly mismatched alloys, a new class of semiconductor materials. In
his most recent work he has shown that the band gaps of GaInN alloys perfectly
match the solar spectrum offering a potential material system for high efficiency,
multijunction solar cells. Dr. Walukiewicz has published over 200 papers,
review articles and book chapters. He is a co-inventor on several patent
applications. Recently he co-edited a special issue of “Semiconductor Science
and Technology” on the properties of group III-N-V alloys.
