Abstract
A Green-function investigation is made of the (complex) band structure and local density of states of superlattices composed of two alternating component crystals, which are modeled by means of the two-band nearly-free-electron approximation. The variation of different superlattice band structures with component-crystal thickness is studied in detail, particular attention being paid to the all-important role played by interface states.Keywords
