MAGNETOEXCITONS IN ZERO-DIMENSIONAL PARABOLIC QUANTUM DOTS

The effects of lateral confinement and strong magnetic fields on the e nergy levels and optical spectra of magnetoexcitons in a disk-like par abolic quantum dot are considered, For a QD which in the absence of a magnetic field B is in the strong confinement regime, a crossover to t he weak confinement regime can be realized when B is increased. Energy spectra and dipole matrix elements of optical transitions in differen t confinement regimes are found.
