NSCI Seminar: Spintronics as an Enabler for a New Paradigm in Computational Technology

Since the emergence of "Moore's Law" scaling for semiconductor transistors 50 years ago, it has been recognized that the exponential increase of transistor density would ultimately come to an end. While this end-point has been extended much farther than originally thought, the limits of scaling are indeed upon us, and improvements in computational speed and efficiency are now mainly being achieved through novel architectures and new physics, rather than through shrinking device size. Looking toward the future, new physics of device operation will play and even more important role. For this reason, spintronics emerges as a promising platform for future computational systems, since it takes advantage of very different physics of device operation that can enable both improved energy efficiency as well as novel computing paradigms. In this talk, I will describe recent advances in spintronic materials and devices, and will show how new device concepts can be realized based upon physical phenomena such as the spin Hall effect, exchange bias interactions and magnetoelectric effects. I will also compare and contrast various novel spintronic architectures both for Boolean and neuromorphic computing platforms. Finally, throughout this talk, I will provide an overview of the ongoing research in C-SPIN, a vertically integrated research center funded by SRC and DARPA, which has the mission of advancing fundamental knowledge of spintronic materials, devices and novel architectures.

Steven J. Koester
Professor, Electrical and Computer Engineering, University of Minnesota-Twin Cities

Dr. Koester received his Ph.D. in 1995 from the University of California, Santa Barbara. From 1997 to 2010 he was a research staff member at the IBM T. J. Watson Research Center and performed research on a wide variety of electronic and optoelectronic devices, with an emphasis on those utilizing the Si/SiGe material system. From 2006-2010 he served as manager of Exploratory Technology at IBM Research where his team investigated advanced devices and integration concepts for use in future generations of microprocessor technology. Since 2010, he has been a Professor of Electrical & Computer Engineering at the University of Minnesota where his research focuses on novel electronic, photonic and sensing device concepts with an emphasis on graphene and other 2D materials. Dr. Koester has authored or co-authored over 200 technical publications, conference presentations, and book chapters, and holds 65 United States patents. He is an associate director for the SRC/DARPA-funded center for spintronic materials interfaces and novel architectures (C-SPIN) and an associate editor for IEEE Electron Device Letters.
