    • In the calculation of the exciton energy, we use a set of parameters for a typical InAs quantum dot: electric constant e - 14.6, electron effective mass me = 0.07m0, and heavy-hole effective mass mh - 0.25m0, with m0 being the electron mass in a vacuum. The intradot Coulomb integral is performed by using the Monte Carlo method. For an efficient calculation, we used a uniformly distributed random number for the z-coordinate and a Gaussian distributed random number for the lateral direction
