Information Processing by Assemblies of Molecules: Directed Self-Assembly, Nonlinear Behavior, Array Architectures

October 20, 2006
Richard A. Kiehl, Department of Electrical and Computer Engineering, University of Minnesota


Abstract:
This talk deals with research toward information processing by assemblies molecular components arranged in locally coupled arrays. I will discuss our recent work on 1) self-assembly of 2D nanocomponent arrays by in situ hybridization to DNA scaffolding, 2) the electrical behavior of alkanethiol//oligo(phenylene-ethynylene) bilayer molecular junctions, and 3) information processing by nonlinear phase dynamics in locally connected arrays. This work illustrates the type of paradigm shift that could lead to computers with high-level capabilities far beyond those of conventional systems.


Bio:
Richard A. Kiehl received the B.S., M.S., and Ph. D. degrees from the School of Electrical Engineering, Purdue University. From 1974 to 1980 he was a member of technical staff at Sandia National Laboratories, where he initiated studies on optical control of microwave semiconductor devices. In 1980 he joined AT&T Bell Laboratories, Murray Hill, as a member of technical staff. He was a leading contributor to the Bell Labs research on heterostructure electronics, particularly heterostructure field-effect transistors. In 1985 he joined IBM as research staff member at the T. J. Watson Research Center and focused his work on III-V and SiGe-based heterostructure CMOS circuitry. In 1993 he became assistant director of the Quantum Electron Device Laboratory at Fujitsu Laboratories Ltd. in Atsugi, Japan, where he lead research on nanoelectronics. He was on the faculty of Stanford University as acting professor of Electrical Engineering from 1996 to 1999, and he is currently the Louis J. Schnell Professor of Electrical & Computer Engineering at the University of Minnesota. He served as associate editor of IEEE Electron Device Letters and was co-editor of the book High Speed Heterostructure Devices of the Academic Press Semiconductor and Semimetals Series. Professor Kiehl is a member of the American Physical Society and the American Chemical Society and a Fellow of the Institute for Electrical and Electronics Engineers.
