چکیده انگلیسی
Within the effective mass approximation the Schrodinger equation is solved by the finite element method for ellipsoidal ZnS/CdSe core-shell quantum dot. The effects induced by the external electric field, by the impurity position and by the geometric shape on the electronic properties of prolate and oblate spheroids core-shell systems are analyzed. The binding energies, the electron shell localization probabilities and the additional polarizability introduced by the shallow donor impurity are obtained and are investigated for various shapes of spheroid core/shell quantum dots.
