Model of optical transitions in A₂B₆ wurtzite type quantum dots
Model of optical transitions in A₂B₆ wurtzite type quantum dots is proposed. It is based on the effective mass approximation and the quantum confinement effects, the valence band degeneracy in G point of the Brillouin zone and the effective mass anisotropy of the holes are also taken into account.
