IBM-Stanford Spintronic Science and Applications Center Scientists

David J. Smith
Regents' Professor of Physics
Arizona State University

Biography
David J. Smith is Regents' Professor of Physics at Arizona State University. He received his Ph.D. in Physics (1978) and D.Sc. (1988) from the University of Melbourne, Australia. He has served as Director, Cambridge University High Resolution Electron Microscope (1980 to1984), Director, NSF National User Facility for High Resolution Electron Microscopy (1991 to 1996), and Director, Center for High Resolution Electron Microscopy at Arizona State University (1991 to 2006). His long-term research interests have centered around atomic-resolution electron microscopy, with a recent focus on characterization of magnetic nanostructures and semiconductor heterostructures. Smith is a Fellow of the Institute of Physics (U.K.) and the American Physical Society, and member of the Materials Research Society, and the Microscopy Society of America, and he received the C.V. Boyes Prize from the Institute of Physics (U.K.) in 1985. He has co-chaired MRS, MSA and RMS symposia, and co-organized several Arizona State University Winter Workshops as well as Lawrence Symposia on Critical Issues in Epitaxy. He has given more than 150 invited lectures and seminars at National/International conferences, workshops, and other institutions, and he has authored/co-authored 20 book chapters and more than 400 refereed journal articles. He is listed by ISI as Highly Cited in Materials Science.

Smith has had a longstanding collaboration with Stuart Parkin and colleagues at IBM Almaden Research Center dating back to the early 1990s. This joint work has focused primarily on microstructural and micromagnetic characterization using electron microscopy-based methods, including electron holography. Initial studies involved magnetic multilayers displaying giant magnetoresistance, and was supported by the IBM Sponsored University Research Program (Dr. Zhigang Li) and an IBM Graduate Fellowship (Anjaneya Modak). Smith also collaborated on the DARPA-funded Spintronics program which explored the development of magnetic tunnel junctions for applications to non-volatile magnetic random access memory (Dr. Rafal Dunin-Borkowski and Hua Wang). More recent work has included investigations of alternate junction barrier materials and novel spin-based devices (Titus Leo).
