A parametrized band structure for the wurtzite crystal is formulated following the tight‐binding interpolation scheme of Slater and Koster. The parametrized secular determinant is factorized using group theory at the symmetry points and axes inside the Brillouin zone. Besides the group theoretic factorization restrictive assumptions regarding the nature of the overlap integrals were needed for further factorization to facilitate the numerical evaluation of the parameters. Using the OPW data of Herman at the high symmetry points γ, A, H, and K, the parameters for wurtzite SiC, ZnS, ZnSe, and ZnTe are found and a thorough study of the energy bands throughout the Brillouin zone for these solids is performed with the help of these parameters.
