Electric Field Induced Optical Gain Of A Hydrogenic Impurity In A Cd_(0.8)Zn_(0.2)Se/ZnSe Parabolic Quantum Dot

摘要

The dependence of electric field on the electronic and optical properties is investigated in a Cd_(0.8)Zn_(0.2)Se/ZnSe quantum dot. The hydrogenic binding energy, in the presence of electric field, is calculated with the spatial confinement effect. The electric field dependent optical gain with the photon energy is found using compact density matrix method. The results show that the electric field has a great influence on the optical properties of II-VI semiconductor quantum dot.
