The International Technology Roadmap for Semiconductors (ITRS) has identified several candidates of emerging research device and circuit technologies, including resonant-tunneling (RTD) and single-electron (SET) devices, quantum-dot cellular automata (QCA), and cellular neural/nonlinear networks (CNN). We will present an overview of these emerging nanotechnologies, with particular emphasis on nanoelectronic circuit architectures which are based on direct physical (electrical or magnetic) interactions between neighboring device structures in cellular arrays. This concept, which was pioneered by our group at Notre Dame, has become known as "quantum-dot cellular automata," and is a different way of representing information on the nanometer scale. We will also discuss various QCA implementations, including semiconductor quantum dots, metallic Coulomb islands, molecules, and magnetic nanostructures.
Biography of Professor Wolfgang Porod |
Dr. Wolfgang Porod is currently Frank M. Freimann Professor of Electrical Engineering at the University of Notre Dame. He received his Diplom (M.S.) and Ph.D. degrees from the University of Graz, Austria, in 1979 and 1981, respectively. After appointments as a postdoctoral fellow at Colorado State University and as a senior research analyst at Arizona State University, he joined the University of Notre Dame in 1986 as an Associate Professor. He now also serves as the Director of Notre Dame's Center for Nano Science and Technology. His research interests are in the area of nanoelectronics, with an emphasis on new circuit concepts for novel devices. He has authored some 300 publications and presentations. Dr. Porod currently serves as the Vice President for Publications on the newly-created IEEE Nanotechnology Council, and has been appointed an Associate Editor for the new IEEE Transactions on Nanotechnology. He is a Fellow of the IEEE.
