In this study, the binding energy of the donor impurity at 1s, 2s and 2p± states in a   parabolic quantum well is calculated variationally within the effective mass approximation as a function of the quantum well width and the external magnetic field. Furthermore, the effects of the magnetic field on the infrared transitions between the hydrogenic states in a parabolic quantum well under are investigated.
