The binding energies are calculated as a function of impurity position. The results show that the dot radius and the parabolic potential have a great effect on the binding energies and there is a linear relationship between the dot radius and impurity shift corresponding to the binding energy maximum. In addition, the binding energies show a strong dependence on the impurity position within the dot. While the binding energies for s-state have the maxima for an on-center impurity case, the binding energy maxima of the p-, d- and f-states take place at different points between the center and edge of the dot (C) 2013 Elsevier Ltd.
