Abstract: Carbon-based nanostructures are promising candidates for nano-electronics due to their natural small scales as well as their mechanical, thermal, and electrical properties. In this talk, I will briefly I will briefly review the technological evolution of the MOS transistor, which is the basic element of microelectronic systems, and address the “end of the road” scenario for silicon technology. I will then discuss some issues related to dissipation in carbon nanotubes for use as interconnects under electric stress, as well as non-linear transport and modeling in graphene field-effect transistors. For this purpose we use a self-consistent approach based on the Boltzmann transport equation in the high field regime within the device geometries, and boundary conditions. I will describe the output characteristics of graphene field effect transistors by using the charge-control model for the current. Closed expressions for the conductance, transconductance and saturation voltage are derived in good agreement with existing experimental data.

Biography：Dr. Jean-Pierre Leburton is the G. Stillman Professor of Electrical and Computer Engineering at the University of Illinois in Urbana-Champaign. He is also Professor of Physics and a full time Research Faculty in the Beckman Institute. Dr. Leburton joined the University of Illinois in 1981 from Germany where he worked as a research scientist with the Siemens A.G. Research Laboratory in Munich. In 1992, he held the Hitachi LTD Chair on Quantum Materials at the University of Tokyo, and was a Visiting Professor in the Federal Polytechnic Institute in Lausanne, Switzerland in 2000. He is involved with research in nanostructures modeling and in quantum device simulation. His present research interest encompasses non-linear transport in quantum wires and carbon nanotubes, and molecular and ionic transport through semiconductor nanopores for biomolecule manipulation and sensing.Professor Leburton is author and co-author of more than 300 technical papers in international journals and books, and served in numerous conferences committees. In 1993 he was awarded the title of “Chevalier dans l’Ordre des Palmes Academiques “ by the French Government. He is a Fellow of the Institute of Electrical and Electronic Engineers (IEEE), the American Physical Society (APS), the Optical Society of America (OSA), the American Association for the Advancement of Science (AAAS), the Electrochemical Society (ECS) and the Institute of Physics (IOP). He is also a member of the New York Academy of Science. In 2004 he was the recipient of the ISCS Quantum Device Award, and of the Gold medal for scientific achievement at the 75th anniversary of the Alumnus association of his Alma mater, the University of Liege, Belgium. He is currently a Distinguished Lecturer for the IEEE Nanotechnology Council for 2010-2011. In 2011 he was elected to Royal Academy of Sciences of Belgium.
