Collective excitations in quantum dots: Calculated Raman spectra

Steffens, O. ; Wensauer, A. ; Rössler, U. ; Suhrke, M.



Abstract

Electronic Raman scattering provides information on excited states, whose collective character as being related to the charge or spin density can be distinguished by using different polarization configurations. We employ time-dependent spin-density functional theory to calculate Raman spectra for circular semiconductor quantum dots with up to 10 electrons for the polarized and depolarized ...
