Carbon nanotubes (CNTs) have extremely unique properties and many potential applications in electronics. The fundamental structure and electronics properties of CNTs will be presented. Our recent work on electron transport in CNTs shows that they may give rise to revolutionary devices in the areas of sensors and wireless communication. More specifically, calculations and experiment indicate that the electron mobility in CNTs can be as much as one hundred times greater than that of silicon. Furthermore, this mobility can be radically changed upon the attachment of an impurity to the CNT, giving rise to an extremely sensitive detector. Furthermore, novel transport calculations predict that CNTs give rise to terahertz current oscillations upon application of a simple DC bias. Such a property has the potential of extending bandwidth by accessing the terahertz part of the spectrum and thus revolutionizing wireless communication. These properties, their physical origins and their implications to everyday life, will be discussed.
Dr. Goldsman received his Ph.D. in electrical engineering from Cornell University. He is currently a professor at the Department of Electrical and Computer Engineering at the University of Maryland where he directs the Semiconductor Device Simulation Laboratory and the Mixed Signal Design Laboratory. He has written two educational texts in electronics for use at the University of Maryland. His research activities include sponsored programs in nanoelectronics, power electronic transistors, radio frequency electronics, and the design of photo-electronic devices. Dr. Goldsman is currently the program chair of the International Semiconductor Device Research Symposium and is a member of the Technical Committee for the International Conference on Simulation of Semiconductor Processes and Devices. He has published more than one hundred fifty peer reviewed papers, and has had research contracts with leading governmental and industrial institutions including Intel Corp, LSI Logic, NSF, NASA, LPS, ARL and NIH.
