A full configuration interaction (FCI) approach for solving the Schrodinger equation for electrons and holes in a strain-induced quantum dot, within the effective-mass approximation, has been developed. The FCI calculations have been performed on a weakly confined quantum dot system containing up to four electron-hole pairs. The results show the importance of correlation effects in reproducing the different features of the experimental quantum dot spectra. It is also shown that the all singles and doubles configuration interaction model, which can be used to study larger systems, is a relatively good approximation to FCI by considering more than 90% of the correlation energy.
