Zusammenfassung

We theoretically investigate the resonant Raman scattering of GaAs quantum dots. The electron system is treated within the time-dependent local-density approximation and the cross section is calculated by including valence-band states as intermediate states in the scattering process. We show that, besides the strongly collective charge-density excitations and spin-density excitations, which ...
