Subsequently, he was a Postdoctoral Research Associate in the Surface Science Center at the University of Pittsburgh, where he performed pioneering experiments with Professors J. T. Yates, Jr. and W. J. Choyke on Si and SiC surface chemistry, epitaxial growth, methods in semiconductor surface chemistry, and electron-stimulated desorption (ESD and ESDIAD) of F⁺ from Si(100) surfaces.

Later, he moved to Intel Corporation, where he was Chief Surface Scientist during development of the 386-486 (pre-Pentium) microprocessor.  During this period the Materials Technology Group at Intel experienced tremendous growth with the addition of nearly $20M of surface, thin film, and materials instrumentation to support advanced VLSI technology.

Currently, Dr. Bozack is Professor of Physics at Auburn University (AU) and Director of the AU Surface Science Laboratory (AUSSL).   His research interests include gas- and metal-surface reactions, semiconductor surfaces, thin films, ohmic and Schottky contact development, semiconductor processing technology, wide bandgap electronics, liquid metal alloy wetting, and Pb-free solder technology.  Current work focuses on the details of chemical reactions between liquid and solid surfaces.  The focus is to obtain a microscopic description of surface dynamic processes by exploring the kinetics of surface reactions and the nature of the surface chemical bond.

Dr. Bozack has published over 150 professional papers related to his research, written 1 book chapter, holds 1 patent, and has won several outstanding physics teacher awards.  He is a member of the American Vacuum Society (AVS), Materials Research Society (MRS), and the American Association of Physics Teachers (AAPT) and is a consultant to numerous large corporations such as the U.S. Customs Research Laboratory, Eagle-Picher Industries, Cessna Aircraft, Aragon Elastomers, Daimler-Chrysler, and Molex, Inc..  For several years he has served as a publications referee for the Journal of Applied Physics, IEEE Transactions, the Journal of Vacuum Science and Technology, and Surface Science Spectra.
