| Abstract | We report exact-diagonalization studies of inelastic light scattering in few-electron quantum dots under the strong-confinement regime characteristic of self-assembled dots. The spectra of intraband excitations of dots with Ne = 2, 3, 4, 5, and 6 electrons are calculated. Collective charge-density and spin-density excitations of the systems are identified by computing the multipolar transition amplitudes and the total spin of each excited state of the dots. We apply the orthodox (second-order) theory for scattering due to electronic excitations. Our numerical results stress the dominance of monopole peaks in Raman spectra and the breakdown of selection rules in open-shell dots. The dependence of these spectra on the number of electrons in the dot and the incident photon energy is explicitly shown. Qualitative comparisons are made with recent experimental results. |
