David Turnbull Lectureship

Phaedon Avouris - IBM T. J. Watson Research Center

Tuesday, November 29 | 5:15 pm
Sheraton Hotel, 2nd Floor, Grand Ballroom  

 Phaedon Avouris
IBM T. J. Watson Research Center (view biography)

Talk Presentation: Graphene -- Applications in Electronics and Optoelectronics (view abstract)

"for his development of nanoscience and nanotechnology through research, publications, lecturing and mentoring: in particular, for his work on carbon nanotubes, graphene and semiconductor surfaces, imaging and measuring their electronic structure and properties; modifying them chemically and physically using scanning probe techniques; and incorporating them into advanced electronic and photonic devices"  

The David Turnbull Lectureship recognizes the career of a scientist who has made outstanding contributions to understanding materials phenomena and properties through research, writing, and lecturing, as exemplified by David Turnbull.  The 2011 Turnbull Lecturer Award will be presented to Phaedon Avouris at the Awards Ceremony at 6:30 pm on Wednesday, November 30 (Sheraton Hotel Grand Ballroom.)   

Phaedon Avouris Biography

Phaedon Avouris received his BSc degree in chemistry from the Aristotle University in Greece (1968) and his PhD degree in physical chemistry from Michigan State University (1974). After postdoctoral work in physical chemistry at the University of California, Los Angeles and AT&T Bell Labs, he joined the IBM Research Division in 1978 and became manager of chemical physics in 1984. He is currently an IBM Fellow and manager of nanoscience and nanotechnology. He has also been an adjunct professor at Columbia University and at the University of Illinois, Urbana-Champaign.

Avouris' research work has had a profound impact on our understanding of the physics, chemistry and applications of nanoscale materials, to such an extent that he can be considered a founder of the fields of nanoscience and nanotechnology. His research contributions to nanoscience, starting with his early work on the physical chemistry of the surfaces of solids with adsorbed atoms and molecules, and leading to his recent work which focuses on carbon nanotubes (CNTs) and graphene for electronics and photonics applications, have added up to over 400 publications and 25,000 citations.

Avouris has also contributed to the development of the field of nanoscience in other ways. He organized an early conference on nanotechnology in 1992, sponsored by NATO and the Engineering Foundation, and edited one of the first books on nanoscience, Atomic and Nanometer Scale Modification of Materials (Plenum, 1993). He has served on the advisory editorial boards of numerous journals devoted to nanoscience and technology and is an editor of the Springer book series on nanoscience. Avouris has published articles explaining nanoscience and nanotechnology in MRS Bulletin, IEEE Spectrum, Physics Today, Materials Today, Accounts of Chemical Research, and Industrial Physicist. He has trained many postdoctoral researchers who have gone onto academic and industrial positions around the world.

Avouris is a member of the American Academy of Arts and Sciences and the Academy of Athens, as well as a senior member of Institute of Electrical and Electronics Engineers (IEEE) and a fellow of the American Physical Society (APS), the U.K. Institute of Physics, the American Association for the Advancement of Science, the American Vacuum Society (AVS), the New York Academy of Science, and the World Technology Network. His honors include the Irving Langmuir Prize for Chemical Physics (American Physical Society), the Medard W. Welch Award (American Vacuum Society), the IEEE Nanotechnology Pioneer Award, the Richard Feynman Prize for Nanotechnology (Foresight Institute), the Richard E. Smalley Prize (Electrochemical Society), the Julius Springer Award for Applied Physics, the AVS Nanotechnology Research Award, the IBM Pat Goldberg Memorial Award, and many IBM Outstanding Technical Achievement awards. 

Turnbull Lectureship Award Talk Presentation - Graphene -- Applications in Electronics and Optoelectronics

Graphene, a two-dimensional, single-atomic-layer material with linear electron dispersion, has rather unique electrical and optical properties. There is strong interest in taking advantage of these properties in technology. After reviewing some of the intrinsic properties of graphene and how they are affected by environmental interactions, I will discuss how they can be utilized in electronics and optoelectronics. Comparisons will be made with the related material, carbon nanotubes.

I will focus most of the discussion on high-frequency graphene transistors and simple integrated circuits, their operational characteristics and related device physics aspects such as carrier transport, the role of electrical contacts, scaling, quantum effects, and power dissipation. I will also review the key optical properties of graphene and provide examples of how these can be used in optoelectronics applications.
