Abstract
Phonon-assisted photoluminescence and Raman scattering have been theoretically studied in nanosize InAs/GaAs disks, which represent a model for self-assembled quantum dots. Optical phonons are considered within a multimode dielectric model taking into account a finite number of vibrational modes in a quantum dot. The dependence of the Raman and the photoluminescence spectra on the size of the quantum dots is analysed. For excitation of quantum dots with radii smaller than the average radius for the statistical ensemble of quantum dots, the ratio of the intensities of the one-phonon to zero-phonon peaks in the photoluminescence spectrum increases.
