Abstract Supercell self-consistent calculation of band structures of (ZnS)n/(Si2)n (110) (n = 2,3,4,5) has been performed by means of linear muffin-tin orbitals method. The valence-band offset of such systems is calculated by frozen optential method and their Joint density of states has been computed by tetrahedron method. Our results show that the (ZnS)n/(Si2)n (110) superlattices have a large valence-band offset and their optical properties integrate exellent optical properties of bulk ZnS and that of Si.
