EFFECTS OF THE IMAGE POTENTIAL ON ELECTRONIC AND IMPURITY STATES IN AQUANTUM BOX

The effects of the image potential on electronic and hydrogenic impuri ty states in a quantum box are investigated using the variational appr oach. The results show that when the image potential is considered, th e variations in ground electronic energy and impurity-binding energy a re considerable, especially when the dimensions of quantum box become small. The results also show that the effects of impurity ion image po tential on impurity-binding energy are much larger than those of elect ron image potential.
