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
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
