摘要：
Rashba and Dresselhaus spin-orbit interactions (SOIs), external fields and dielectric environment effects on hydrogenic impurity states in core-shell (ZnO/ZnS) and inverted core-shell (ZnS/ZnO) quantum dots were studied. We employed the finite difference method to achieve energy eigenvalues of the system. Our results demonstrate that SOIs, external fields and dielectric environment change drastically the impurity states. Besides, the spin degeneracy is removed when both the SOIs and the Zeeman effect are simultaneously considered.
