The effects of mixing between the \(\Gamma\) and \(X\) valleys of the conduction band on the binding energy of a shallow donor in a thin type I AlAs/GaAs quantum well are investigated. The multivalley effective mass equations are solved variationally, with a separable hydrogen-like trial function. T

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

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
