The binding energies of hydrogenic impurity states with an impurity atom located at the center of a two-dimensional circular quantum dot confined by an infinite barrier potential are studied as a function of the dot radius and of the screening parameter in the potential. Accurate binding energies ar
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
