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(omega) through a disordered planar interface between two identical semiinfinite leads. At high frequencies T(omega) exhibits a strong frequency dependence which is determined by the correlation length of the disorder.
