Role of Coulomb correlations in the optical spectra of semiconductor quantum dots
arXiv:cond-mat/0005253 · doi:10.1002/1521-3951(200009)221:1<19::AID-PSSB19>3.0.CO;2-L
Abstract
We present a consistent theoretical description of few-particle effects in the optical spectra of semiconductor quantum dots, based on a direct-diagonalization approach. We show that, because of the strong Coulomb interaction among electrons and holes, each configuration of the confined few-particle system leads to its characteristic signature in the optical spectra. We discuss quantitative predictions and comparison with experiments for both absorption and luminescence.
