Joerg Appenzeller

Dr. 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 Scientist, exploring the ultimate scaling limits of silicon MOSFET devices. From 2001 until 2007, he had 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 and silicon nanowires for a future nanoelectronics. Since 2007 he is Professor of Electrical and Computer Engineering at Purdue University and Scientific Director of Nanoelectronics in the Birck Nanotechnology Center. His current interests include novel devices based on low-dimensional nano-materials as nanowires, nanotubes and graphene.
