The effects of an applied magnetic field of arbitrary strength on shallow donor impurity states in a parabolic quantum dot are theoretically studied. The shifted 1/N-expansion method is used to solve the impurity effective-mass Hamiltonian. The transition energies between the impurity ground and the

Using a variational procedure within the effective-mass approximation we have calculated the binding energies of shallow-donor impurities in cylindrical GaAs quantum-well wires, in an axial magnetic field and an infinite confinement potential. In contrast to the previous results in quantum wells, we

The binding energies of shallow hydrogenic donor impurities in GaAs±(Ga,Al)As quantum boxes are calculated as a function of the size of the structure and as a function of the intensity of an applied electric field. The calculations are performed within the effective-mass approximation and using a va

Within the effective-mass approximation a simple method to calculate the spectra of a shallowdonor impurity in GaAs±(Ga, Al)As cylindrical quantum-well wires (QWWs) suitable for any confinement potential shape in radial direction is proposed. A trial function is taken as the product of a hydrogenic
