Graphene: Applications in Photonics and Plasmonics
Abstract: I will first discuss the basic electronic properties of graphene and its potential applications in electronics. I will present examples of high frequency analog graphene devices and circuits and evaluate the prospects of a commercial RF graphene technology. I will then focus on the optical properties and possible applications of graphene in photonics and plasmonics. I will review the basics of the single particle and collective excitations of graphene, discuss the mechanisms of photocurrent generation in graphene and the design and characteristics of graphene-based photodetectors. I will show that the coupling of light to localized graphene plasmons provides an excellent way of enhancing the strength of graphene-light interaction. Plasmon excitations in graphene micro- and nano-structures and their use in graphene devices in the mid-IR, far IR and THz ranges of the spectrum will be discussed. The interactions of graphene plasmons with intrinsic graphene and substrate phonons and the resulting damping mechanisms also will be analyzed.
Biography: Phaedon Avouris received his B.Sc. in Chemistry from the Aristotle University in Greece in 1968 and his Ph.D. degree in Physical Chemistry from Michigan State University in 1974. After postdoctoral work at UCLA and AT&T Bell Labs he joined the IBM Research Division as a research staff member in 1978. He became manager of Chemical Physics in 1984.
Dr. Avouris is currently an IBM Fellow and manager of Nanoscience & Nanotechnology at the IBM T.J. Watson Research Center in Yorktown Heights, New York. During his time at IBM he has also been Adjunct Professor at Columbia University and at the University of Illinois, Urbana-Champaign.
Avouris has made many outstanding experimental and theoretical contributions to nanoscale science and technology. These contributions span a variety of subjects and have played a critical role in the progress of this field in the last 30 years. He has published about 500 papers on the atomic-scale physics and chemistry of surfaces, and the electrical, optical and opto-electronical properties and devices of carbon nanostructures. His papers have received over 50,000 citations.
Dr. Avouris has worldwide recognition for his continuous leadership in the field of Nanoscience. He is a member of the American Academy of Arts and Sciences (2003), corresponding member of the Academy of Athens (2005), an IBM Fellow (2004) and a honorary Ph.D. from the International Hellenic University. He is the recipient of many awards including the Irving Langmuir Prize for Chemical Physics (American Physical Society, 2003), the David Turnbull Lectureship (Materials Research Society, 2011), the Medard W. Welch Award (American Vacuum Society, 1997), the Institute of Electronic and Electrical Engineers (IEEE) Nanotechnology Pioneer Award (2010), the Richard Feynman Prize for Nanotechnology (Foresight Institute, 1999), the Richard E. Smalley Prize (Electrochemical Society, 2009), the Julius Springer Award for Applied Physics, the AVS Nanotechnology Division Research Award (2011), the Distinguished Alumnus Award of Michigan State University (2001) and numerous Outstanding Technical Achievement IBM awards. He has been elected Fellow of the American Physical Society, the Institute of Physics of the U.K., the American Association for the Advancement of Science, the Materials Research Society, the American Vacuum Society, the New York Academy of Sciences, the World Technology Network and is a Senior Member of IEEE.
