Abstract

One-dimensional nanostructures such as carbon nanotubes and nanowires have attracted considerable interest recently due to their unique electrical and structural properties. In this course, we will discuss some of the most important aspects of CNT based electronics, from the bandstructure to fundamental transport characterizations to high performance transistors. In addition, the one-dimensional systems are attractive to novel architectures such as crossbar memories and logic that offer large connectivity and reconfigurability and are suitable for neuromorphic computing. Several nanotube and nanowire-based crossbar systems will be discussed.

Biography





Wei Lu received the B.S. degree in physics from Tsinghua University, Beijing, China, in 1996, and the M.A. and Ph.D. in physics from Rice University, Houston, TX in 1999 and 2003, respectively. From 2003 to 2005, he was a postdoctoral research fellow at Harvard University, Cambridge, MA. In 2005, he joined the faculty of the Electrical Engineering and Computer Science Department at the University of Michigan as an assistant professor. His research interests lie in the application and fundamental understanding of nanostructures and nanodevices, including high-density crossbar memory and logic devices, semiconductor nanowire based transistors and sensors, flexible and transparent thin-film electronics, and nano-electromechanical systems. He has over 20 refereed journal publications and 3 patents, served as a reviewer and on the editorial board for 17 journals, and he is an active member in several international committees worldwide. He is a member of the IEEE, APS, MRS, and a board member of the AVS Michigan Chapter. He received the Wilson Award in 2003.
