Graphene is a material with interesting electronic properties and one that is currently receiving great attention as a potentially useful material for novel electronic devices. It is also a simple material that provides a concrete example for illustrating how to apply the concepts from electronics from the bottom up to current research problems. The purpose of this short course is to introduce students to this fascinating research topic as well as to develop their skill in problem solving using the tools and techniques of electronics from the bottom up.


Joerg Appenzeller Joerg Appenzeller received the M.S. and Ph.D. degrees in physics from the Technical University of Aachen, Germany in 1991 and 1995. His Ph.D. dissertation investigated quantum transport phenomena in low dimensional systems based on III/V heterostructures. He worked for one year as a Research Scientist in the Research Center in Juelich, Germany before he became an Assistant Professor with the Technical University of Aachen in 1996. During his professorship he explored mesoscopic electron transport in different materials including carbon nanotubes and superconductor/semiconductor-hybride devices. From 1998 to 1999, he was with the Massachusetts Institute of Technology, Cambridge, as a Visiting Scientists, exploring the ultimate scaling limits of silicon MOSFET devices. Since 2001, he has been with the IBM T.J. Watson Research Center, Yorktown, NY, as a Research Staff Member mainly involved in the investigation of the potential of carbon nanotubes for a future nanoelectronics.

Supriyo Datta Supriyo Datta received his B.Tech. from the Indian Institute of Technology in Kharagpur, India in 1975 and his Ph.D. from the University of Illinois at Urbana-Champaign in 1979. In 1981, he joined Purdue University, where he is (since 1999) the Thomas Duncan Distinguished Professor in the School of Electrical and Computer Engineering. He started his career in the field of ultrasonics and was selected by the Ultrasonics group as its outstanding young engineer to receive an IEEE Centennial Key to the Future Award and by the ASEE to receive the Terman Award for his book on Surface Acoustic Wave Devices.

Since 1985 he has focused on current flow in nanoscale electronic devices and is well-known for his contributions to spin electronics and molecular electronics. Datta’s most important contribution, however, is the approach his group has pioneered for the description of quantum transport far from equilibrium, combining the non-equlibrium Green function (NEGF) formalism of many-body physics with the Landauer formalism from mesoscopic physics as described in his books Electronic Transport in Mesoscopic Systems (Cambridge, 1995), and Quantum Transport: Atom to Transistor (Cambridge, 2005).


Datta’s unique approach to the problem of quantum transport has not only had a significant impact on nanoelectronics research but also on graduate and undergraduate curriculum development in the area. He is a Fellow of the American Physical Society (APS) as well as the Institute of Electrical and Electronics Engineers (IEEE) and has received IEEE Technical Field Awards both for research and for graduate teaching.


Mark Lundstrom Mark Lundstrom is the Don and Carol Scifres Distinguished Professor of Electrical and Computer Engineering at Purdue University. He was the founding director of the Network for Computational Nanotechnology and now serves as chairman of its Executive Committee. Lundstrom earned his bachelor’s and master’s degrees from the University of Minnesota in 1973 and 1974, respectively and joined the Purdue faculty upon completing his doctorate on the West Lafayette campus in 1980. Before attending Purdue, he worked at Hewlett-Packard Corporation on MOS process development and manufacturing. At Purdue, he has worked on solar cells, heterostructure devices, carrier transport physics, and the physics and simulation of nanoscale transistors. His current research interests focus on the physics and technology of energy conversion devices. Lundstrom is a fellow the Institute of Electrical and Electronic Engineers (IEEE), the American Physical Society (APS), and the American Association for the Advancement of Science (AAAS). He has received several awards for his contributions to research and education and is a member of the U.S. National Academy of Engineering.
