Abstract:

Surface plasmons, predicted by Rufus Ritchie in 1957 are the key ingredient of plasmonics, and have led in recent years to numerous applications, ranging from optics to medicine. A brief historical background of the pre-surface plasmon plasmonics, and its connection to plasma and particle physics will be followed by a discussion of the various surface plasmons at metallic surfaces. It will be shown how understanding of the electromagnetic response of nanostructures and metamaterials can benefit from earlier studies of plasmons in the semiconductor heterojunctions, quantum wells, and quantum dots. I will also discuss briefly the response of graphene, as well as carbon nanotubes, with their numerous van Hove, 1D, 3D plasmons, as well as plasmarons.

Short bio:

Dr. Krzysztof Kempa received his Master of Science degree from the Institute of Electron Technology of the Technical University in Wroclaw (Poland) in 1973, and the PhD degree from the University of Wroclaw in 1980. Presently a Full Professor of Physics at Boston College, he co-authored over 100 peer reviewed papers, gave over 40 invited talks and seminars, and has over 10 patents in the field of semiconductor devices, nano-optics, and photovoltaics. His Visiting Professor appointments included the Free University Berlin (Germany), Technical University of Vienna (Austria), and the Imperial College in London (England). Currently, he is a Distinguished Visiting Professor at the South China Normal University in Guangzhou (China). He co-organized the NT02 International Conference on Science and Applications of Nanotubes, Boston 2002, and co-founded NanoLab, Inc., a nanotech company which manufacturers carbon nanotubes and related products (www.nano-lab.com). His research interests are in the field of plasmonics, nano-photovoltaics, and metamaterials.
