Phonon influence on emission spectra of biexciton and exciton complexes in semiconductor quantum dots

The effect of longitudinal optical (LO) phonon on the emission spectra of biexciton and exciton complexes in semiconductor quantum dots (QDs) is theoretically investigated. The predicted resonantly excited photoluminescence of linearly polarized light in cylindrical InAs/AlAs QD nanostructure is compared with the experimental results. The exciton and biexciton binding energies are computed and appearance of LO phonon replicas in the photoluminescence spectra of the nanostructure is discussed
