1999 JAMES C. McGRODDY PRIZE IN NEW MATERIALS

to

Eugene E. Haller
University of California, Berkeley

Citation:
"For innovations in growing diamond and germanium crystals with unprecedented control of chemical and isotopic purity and perfection, and for creative leadership and active participation in worldwide collaborations based on these extraordinary materials resulting in both fundamental discoveries and new technological applications."

Background:
Dr. Haller is Professor of Materials Science at the University of California at Berkeley and jointly holds a faculty senior scientist position at the Lawrence Berkeley National Laboratory. He received his diploma (1967) and doctorate (1970) in nuclear and solid state physics, respectively at the University of Basel, Switzerland. In 1971 he joined the Lawrence Berkeley Laboratory to perform research in ultra-pure semiconductors. He identified the first electrically active, hydrogen-related centers in a semiconductor, a phenomenon subsequently widely studied in this class of materials. In 1980 he joined the UC Berkeley faculty. His research focuses on semiconductor crystal growth, advanced doping and defect problems, the metal-insulator transition, and far-infrared detectors and coherent sources. In 1990 he initiated research with isotopically enriched semiconductors. A broad range of studies with these materials of phonons, solid state diffusion, local vibrational mode spectroscopy, and the metal-insulator transition are being conducted worldwide.

Dr. Haller held visiting positions at the Max-Planck-Institute, Stuttgart and at the Imperial College, London. He is a Fellow of the APS, a member of MRS and the Swiss Physical Society.

He has won the Alexander von Humboldt US Senior Scientist Award (1986), a Professorship at the Miller Institute for Basic Research (1990) and, together with Manuel Cardona, the Max-Planck Research Award (1994).
