摘要：
The exciton-LO-phonon interaction in self-organized quantum dots is investigated emphasizing the impact of realistic structural properties. The possibility to engineer the local charge density via the shape and composition profile of such strained quantum dots provides an unique opportunity to optimize the electronic and optical properties of a semiconductor nanostructure. Size-selective luminescence, resonant Raman scattering, and time-resolved luminescence experiments provide insight into the exciton-LO-phonon and exciton-photon couplings in self-organized quantum dots. The impact of the structural details is analyzed based on eight-band k(.)p model calculations.
