David Aspnes

from Wikipedia, the free encyclopedia

David Erik Aspnes (born May 1, 1939 in Madison , Wisconsin ) is an American physicist .

He graduated from the University of Wisconsin-Madison with a bachelor's degree in 1960 and a master's degree in 1961 and received his doctorate in 1965 from the University of Illinois at Urbana-Champaign . He was a post-doctoral student at the University of Illinois and Brown University . From 1967 he was at Bell Laboratories and their successor Bellcore, where he was head of the interface physics department. In 1992 he became a professor of physics at North Carolina State University .

He deals with optical spectroscopy and physics of semiconductors and surfaces. He developed the method of low field electroreflectance for high-resolution spectroscopy of semiconductors and determination of their band structure, spectroscopic ellipsometry for studying thin films and surfaces, for example, and reflectance-difference spectroscopy for real-time analysis of epitaxy .

In 1987 he received the RW Wood Prize , in 1996 the Frank Isakson Prize for his creative applications of experimental and theoretical methods for the study of the optical properties of thin films, surfaces and interfaces and specifically for electric field modulation, spectroscopic ellipsometry and dynamic control of epitaxy and in 1997 the Max Planck Research Award . He is a Fellow of the American Physical Society and the Optical Society of America . In 1998 he became a member of the National Academy of Sciences and in 2002 of the American Association for the Advancement of Science . He received an Alexander von Humboldt Senior Scientist Award in 1976 and the Medard W. Welch Award in 1998 .

He is the father of James Aspnes , who is a computer science professor at Yale University .
