Energy band structures ZnSe–ZnTe and ZnS0.5Se0.5–ZnTe superlattices are calculated using the Kronig‐Penney model taking into account strain effects due to the lattice mismatches between the materials. The ZnSe(30 A˚)–ZnTe(5 A˚) and the ZnS0.5Se0.5(30 A˚)–ZnTe(5 A˚) superlattices have energy gaps of 2.5 and 2.7 eV, respectively. The ZnS0.5Se0.5(30 A˚)–p‐type ZnTe(5 A˚) superlattice is considered to be ap‐type material of 1017cm−3and to be available for a hole injection layer to ann‐type ZnSe layer.
