Dr. Wladek Walukiewicz

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.
