| 中文摘要 | in the framework of the effective-mass envelope-function theory, the electronic and optical properties of a spherical core-shell quantum-dot quantum well (qdqw) structure with one and two wells have been investigated. the results show that the energies of electron and hole states depend sensitively on the well thickness and core radius of quantum-dot quantum well structure. an interesting spatially separated characteristic of electron and hole in qdqw is found and enhanced significantly in the two-wells case. the normalized oscillator strength for the optical transition between the electron and hole states in qdqw exhibits a deep valley at some special well thickness. the coulomb interaction between the electron and hole is also taken into account.
