Exciton and biexciton states in realistic quantum dots are investigated theoretically. The few-particle interactions are shown to depend sensitively on the structural properties of the dots. The state energies are obtained by a configuration interaction method added on eight-band k · p calculations of single-particle states. By comparing the calculations to empirical pseudopotential ones, the accuracy of the method is established.
