    • Creation of biexcitons via resonant excitation of QD’s is also possible since biexciton and exciton states may be degenerated in energy for particular QD shapes and compositions. We note, however, that there is no reason to expect that this degeneracy exists for all types of QD’s having the same ground-state transition energy. As we study QD’s of various shapes and compositions even under the resonant excitation conditions, this coincidence may be expected only for a fraction of QD’s. As the possible coexistence of degenerate biexciton and exciton states does not principally change our argumentation, we restrict our discussion at that point to just mentioning the general possibility of this effect
