Rudolf (Rudy) Ludeke is an industrial physicist whose expertise includes semiconductor science, materials growth and the physical characterization of surfaces and interfaces. He retired from IBM's Research Division in Yorktown Heights, New York in 2006 after a 38-year career in research and management. Among the highlights of his career are his co-invention of the semiconductor superlattice, the first demonstration of its achievability through controlled deposition using molecular beam epitaxy and fundamental advances in ballistic electron emission spectroscopy and electrostatic (Kelvin) force microscopy.
A Fellow of the American Physical Society, Ludeke is also an Honorary Member of the American Vacuum Society (AVS), the highest accolade bestowed on AVS members for technical achievement and service to the society. He is a past president of AVS and served on the AVS Board of Directors. An enthusiastic advocate for industrial outreach, Ludeke has championed the AIP-sponsored Industrial Physics Forum (IPF) for several years. He is a graduate of the University of Cincinnati and received MA and PhD degrees in Applied Physics from Harvard University. During his career at IBM, he spent a sabbatical year as an Alexander von Humboldt fellow at the Max-Planck-Institute for Solid State Physics in Stuttgart, Germany.
