R. G. Herb Condensed Matter Seminar
Raman scattering in molecular junctions
Time: 10:00 am
Place: 5310 Chamberlin
Speaker: Michael Galperin, University of California, San Diego
Abstract: Recent advances in experimental techniques at nanoscale, and in particular Raman scattering measurements on current-carrying single molecule junctions promises to become a superior diagnostic tool. Theoretical understanding of optical response of open molecular systems far from equilibrium is of major importance for development of molecular optoelectronic devices. Within simple models we consider intra-molecular and charge-transfer contributions to Raman spectroscopy of molecular junction. We also discuss a concept of "effective temperature", its relevance in representation of bias-induced heating, and ability of Raman measurements to provide information on the latter.
Host: Irena Knezevic & Robert Joynt
