In this study, we have calculated the donor impurity binding energy, donor impurity related photoionization cross-section and polarizability in symmetric GaAs/Ga1-xAlxAs quantum well-wire as a function of the impurity positions, dimensions of the structures and external electric and magnetic field, the calculations were performed within the effective mass approximation, using a variational method.
