Abstract
Carbon nanotubes, since their discovery by Ijima in 1991, has garnered significant amount of interest owing to their fascinating properties. The high current carrying capacity of the metallic carbon nanotubes make them an ideal candidate for future interconnects while the high aspect ratio and partially conducting behavior of semiconducting carbon nanotubes have proved to be useful for making field-effect transistors, logic circuits, sensors, and field emitters. The exceptional thermal properties of carbon nanotubes and the numerous diverse applications have made this area extremely exciting. Despite the current progress in nanotube synthesis and the promise and need for high performance, miniature nanosystems, several challenges remain prior to the realization of nanotube based systems. Furthermore, combining nanomaterials with Complementary Metal Oxide Semiconductor (CMOS) technology, not only enables novel high performance applications, but also will produce miniature portable nanosystems of the future. In addition, using solution based processing methods, nanotube based devices can be readily realized on polymeric substrates for low cost, large area electronics and/or sensor applications. The first part of my talk will focus on integration of nanotubes onto a CMOS platform for sensing applications. In the second part, I will focus on flexible nanoelectronics using carbon nanotubes.

Biography
Mehmet R. Dokmeci received B.S. (with distinction) and M.S. degrees from the University of Minnesota, Minneapolis and the Ph.D. degree from the University of Michigan, Ann Arbor, all in Electrical Engineering.
