Abstract

For an FCC crystal with central force interactions and separately for a scalar model on a square lattice, we compute exactly the phonon transmission coefficient T(ω) through a disordered planar interface between two identical semi-infinite leads. At high frequencies T(ω) exhibits a strong frequency dependence which is determined by the correlation length of the disorder.
