Biography: Antoine Kahn was born in Metz, France, on February 27, 1951. He graduated from the Ecole Polytechnique de Grenoble in 1974. He received the M.S.E. and Ph.D. in Electrical Engineering and Computer Science from Princeton University in 1975 and 1978 respectively. He joined the faculty in September 1979 and is doing research in the field of semiconductor surfaces and interfaces. Over the past five years, his research has emphasized inorganic wide band gap semiconductors and organic molecular solids. In 1984, he was a recipient of a five year Presidential Young Investigator Award and was elected Fellow of the American Vacuum Society in 1999.
