| 中文摘要 | the electronic structure of diluted magnetic semiconductor (dms) superlattices under an in-plane magnetic field is studied within the framework of the effective-mass theory; the strain effect is also included in the calculation. the numerical results show that an increase of the in-plane magnetic field renders the dms superlattice from the direct band-gap system to the indirect band-gap system, and spatially separates the electron and the hole by changing the type-i band alignment to a type-ii band alignment. the optical transition probability changes from type i to type ii and back to type i like at large magnetic field. this phenomenon arises from the interplay among the superlattice potential profile, the external magnetic field, and the sp-d exchange interaction between the carriers and the magnetic ions. the shear strain induces a strong coupling of the light- and heavy-hole states and a transition of the hole ground states from "light"-hole to "heavy"-hole-like states. |
