    • It has been pointed out that the electron and hole are spatially separated in multi-stacked InP QDs; In this case, the center of the wave function of the hole exists outside of the QDs: M. Hayne, R. Provoost, M.K. Zundel, Y.M. Manz, K. Eberl, and V.V. Moshchalkov, Phys. Rev. B 62, 10324 (2000); M. Hayne, M. Maes, V.V. Moshchalkov, Y.M. Manz, O.G. Schmidt, and K. Eberl, Appl. Phys. Lett. 79, 45 (2001); Such a large separation was, however, not observed in the single-layered InP QDs used in this study. The separation is much smaller than the QD size.

    • Besombes et al. have recently observed the Stark shift of the neutral and charged exciton states in CdTe QDs. They found that each state has different value of the Stark coefficient: L. Besombes, K. Kheng, L. Marsal, and H. Mariette, Phys. Rev. B 65, 121314(R) (2002).

    • note
    • It should be mentioned that we have measured the Stark shift under both weak (less than 0.1 excitons/dot) and strong (about 1 exciton/dot) excitation conditions to examine the effect from excess carriers on both inside and outside of the QDs. However, a significant difference was not observed in the Stark coefficients.

    • 36 In our case, however, such a splitting was not observed probably because of the small g-value in InP QDs.
