The electronic structure of twinning boundaries in micro-crystals was calculated by using the empirical pseudopotential method, and super-cell techniques. Interface bound states within the bulk band-gap were found in several cases. The most prominent one was above the valence band top at the M-point of the interface Brillouin zone for the cationic interface. Electronic Structure of AgBr(111) Twin Boundaries.
