Dynamic electronic response in Nanoscale structures
Department of Physics,
In this talk, I will present our theoretical studies of dynamic response of electrons in nanoscale structures. A dynamic standing Friedel wave and a standing spin wave were discovered, analogous to the static Friedel oscillations. The wavelength of the standing Friedel wave is controlled by the external driving frequency and the Fermi velocity of the nanoscale structure. A effective model of capacitance of nanoscale structures between two electrodes were proposed based on the dynamic electronic response.
