We employ a microscopic model of AlSb/InAs superlattices to study their dynamical characteristics and the effect of interface bond type. The localization of valence band-edge states at InSb-like interfaces is observed, and we use the elastic scattering cross-section of substitutional defects to probe the superlattice bandstructures. The variation of the scattering properties provides an unambiguous signature of the localized interface states that exist in our model.
