Abstract
We have studied the electronic properties of single twin boundaries an d twinning superlattices in lead sulfide. The results are compared aga inst those obtained previously for such structures based on diamond/zi ncblende type materials, and substantial differences are noted. It is found that lead sulfide twinning superlattices can have significantly wider or narrower band gaps than the homogeneous material, depending o n whether the twin interface is occupied by anion or cation atoms.
