Carbon Nanotubes and Graphene:
Prospects in Electronics and Photonics

by Phaedon Avouris

Sunday, April 25, 2010 | Vancouver, Canada

Phaedon AvourisNanoscience/nanotechnology is currently one of the most active areas of research. At the nanometer scale, and in reduced dimensionality, materials acquire novel properties. This motivates the synthesis, manipulation, study, and search for new applications of nanostructures. Among these, carbon-based nanostructures such as carbon nanotubes and graphene are attracting special attention. Graphene and carbon nanotubes are strongly bound, covalent materials, with the carbon atoms arranged in a hexagonal honeycomb lattice to form two-dimensional and one-dimensional nanostructures, respectively. As a result of their structure and low dimensionality, these one-atom thick structures have some rather unique electrical and optical properties that recommend them for a host of different applications in electronics and photonics. In this talk we will examine these properties and also demonstrate model electronic devices such as ultra-fast transistors and optical detectors, infrared light emitters, and simple integrated circuits. We will discuss the advantages of these devices and also the hurdles that remain before they can be integrated into mature, competitive technologies.

Phaedon Avouris is an IBM Fellow and manager of Nanoscience & Nanotechnology at the IBM, T. J. Watson Research Center in Yorktown Heights, NY (U.S.). He received his BSc at the Aristotle University in Greece and his PhD in Physical Chemistry at Michigan State University in 1974. He did postdoctoral work at UCLA and was a Research Fellow at AT&T Bell Laboratories before joining the staff of IBM's Research Division at the Watson Research Center in 1978.

Over the years, he has worked in a wide range of research areas: laser spectroscopy, surface physics/chemistry, scanning tunneling microscopy, atom manipulation, and nanoelectronics. His current research focuses on experimental and theoretical studies of the electronic and photonic properties of carbon nanotubes and graphene. The work also includes the design, fabrication, and study of nanoelectronic and optoelectronic devices based on these materials.

Dr. Avouris has published over 390 scientific papers. He has been elected Fellow of the American Academy of Arts and Sciences, the American Physical Society, the Institute of Physics of the U.K., the Academy of Athens (National Academy of Greece), the IBM Academy of Technology, American Association for the Advancement of Science, New York Academy of Sciences, and the American Vacuum Society. He has received many awards including the APS Irving Langmuir Prize for Chemical Physics, the AVS Medard W. Welch Award for Surface Science, the Julius Springer Award for Applied Physics, the Richard E. Smalley Research Award of ECS, and the Richard Feynman Nanotechnology Prize. He has also received many IBM Corporation “Outstanding Technical Achievement” awards. He serves in the editorial boards of a number of journals and book series.
