David Keane Ferry (born 1940) is the Regents' Professor of Electrical Engineering at Arizona State University (ASU), notable for his research in semiconductor devices. He received his BSEE, 1962, and MSEE, 1963, both from Texas Technical College. Ferry obtained his PhD under Arwin A. Dougal, 1966, from the University of Texas at Austin with a thesis entitled Anomalous Microwave Emission from Bulk Semiconductors. Following a postdoctoral year in Vienna (1966–67) under Karl-Heinz Seeger, he spent time at Texas Tech University (1967–73), the Office of Naval Research (1973–77), Colorado State University (1977–83), and then joined Arizona State University in 1983. He has received a number of honours including the IEEE Cledo Brunetti Award, 1999; IEEE (Phoenix) Engineer of Year, 1990; Fellow of the IEEE, 1987; Fellow of the American Physical Society, 1974; and Fellow of the Institute of Physics, 2008. His research involves the physics and simulation of semiconductor devices and quantum effects and transport in mesoscopic device structures.
In 2018, he co-authored a book on The Wigner Function in Science and Technology, a review article on Recent Advances in Wigner Function Approaches. In 2015, he co-edited the Special Issue on Wigner Functions in the Journal of Computational Electronics. He is a co-founder of the Wigner Initiative (where he is also in the steering committee) and the International Wigner Workshop (IW2) series (which he co-organizes).
