Electric field effect on the Raman scattering of a hydrogenic impurity in spherical quantum dot

Using the perturbation method and the effective mass approximation, we studied the combined effects of impurity and external electric field on Raman scattering in a spherical quantum dot with a parabolic potential. Based on the computed energies and wave functions, the differential cross-section involved in this process is investigated, and the selection rules are also calculated. Our results suggest that the scattering intensity is strongly affected by the impurity and external electric field considered in this work.

► The impurity has a drastic effect on the Raman scattering. ► The external electric field has an obvious effect on Raman scattering. ► The contribution of confinement potential to DCS is more than that of electric field.
