摘要：
The binding energy of hydrogenic impurity located at the center of elliptical quantum wire using the effective mass approximation and an appropriate coordinate transformation is calculated for CdS/SiO2 structure. The effect of surface polarization charges due to impurity on the impurity binding energy is considered. The results clearly indicate that the binding energy depends not only on the polarization charges but also on the ellipticity constant. (C) 2013 Elsevier Ltd. All rights reserved.
