Abstract
The electronic band structures of both common-anion and common-cation II-VI superlattices (SL) were investigated using sp3s*tight-binding method. The strained CdTe/ZnTe(001), ZnS/ZnSe(001), and ZnSe/ZnTe(001) superlattice models were considered for the study. The biaxial strain were found to contribute in the valence-band splittings and yielded type-I SLs. The results show that for the type-II SLs, strain can confine the charge carrier near the interface and thus enhances the radiative efficiency.
