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
Using the potential morphing method in the effective mass approximation, we have studied the behavior of the impurity binding energy as a function of the impurity position, for different applied electric fields, different Al concentrations at the well center, in strong, intermediate and weak confine
