The effect of polytypism on the band structure of SnS2

Abstract
The energy band structure of 4H-SnS2 has been calculated using the local pseudopotential method in such a way that a direct comparison can be made with the band structure of 2H-SnS2 by Powell, Liang and Chadi (ibid., vol.11, p.885 (1978)). In particular, the two band structures are compared for the electron states in the vicinity of the band gap. The calculated band gap is found to be smaller in 4H-SnS2 than in 2H-SnS2, and this is in qualitative agreement with experiment.
