The electronic properties of single twin boundaries, and of superlattices which were based upon them, were calculated. It was noted that there were appreciable differences between these results, and those of a similar study that had been based upon zincblende-type semiconductors. It was found that such superlattices could have band-gaps that were wider or narrower than that of the homogeneous material.
