Within the effective-mass approximation a simple method to calculate the spectra of a shallowdonor impurity in GaAsยฑ(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

The magneto-optical absorption spectrum of a \(D^{-}\)ion in a \(\mathrm{GaAs}_{-} \mathrm{Ga}_{0.75} \mathrm{Al}_{0.25} \mathrm{As}\) quantum well is calculated. We used the variational method based on a two orbital picture of a \(D^{-}\)ion, in which each single electron orbital is represented by
The binding energy of a donor impurity in a spherical GaAsยฑ(Ga,Al)As quantum dot with parabolic confinement is calculated as a function of the radius of the quantum dot and as a function of the intensity of an applied electric field. Calculations are performed within the effective-mass approximation
