A Landau-Pekar variational theory is employed to obtain the ground and the first excited state binding energies of an electron bound to a Coulomb impurity in a polar semiconductor quantum dot (QD) with parabolic confinement in both two and three dimensions. It is found that the binding energy increa
Effect of external electric field on the excited state energies in a spherical quantum dot is considered. The impurity energy and normalized binding energy are calculated using variational method within the effective mass approximation and finite barrier potential. The results show the energies decr
