Abstract
The contribution to the biexciton binding energy in quantum dots resulting from the interaction with longitudinal optical phonons is estimated by performing the configuration-interaction calculation of the few-particle states in a simple model of the confining potential and by including the phonon corrections by means of a perturbation theory. It is found that the polaron contribution tends to compensate the Coulomb-related biexciton shift (binding energy) and reduces its value by up to 30%, depending on the material parameters of the system.
