Abstract
Using the effective mass approximation (E.M.A), we have performed theoretically the influence of the capped matrix, the geometrical parameters and the applied electric intensity on the Polarizability and photoionization cross-section (PCS) of CdS/ZnS core/shell quantum dots CSQDs. The energy states of the binding energy (BE) and their corresponding wave functions are computed by solving Schrödinger equation in three-dimensional based on the variational approach. Our numerical results show that the EF and the nature of dielectric medium have an obvious influence on the BE, PCS and Polarizability of the structure. The present study suggests that the c/s nanostructure dispersed in a dielectric matrix may improve the performance of optoelectronic and photonic devices.
