Full configuration interaction calculations of electron-hole correlation effects in strain-induced quantum dots

The electron-hole correlation effects on the energy levels and the wave fun ctions of a strain-induced quantum dot containing 1, to 10 electron-hole pa irs have been studied using large scale configuration-interaction calculati ons. The results show the importance of including the correlations in order to reproduce the experimentally measured quantum dot spectra and to obtain bound multi-exciton complexes. Increasing the number of electron-hole pair s in the quantum dot a transition from a strongly correlated system to the one approximated by the Hart-ree-Fock theory is observed.
