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
