In partial transmission any diamond phonon can eat a metal phonon, even diamond phonons with frequencies far higher than can exist in the metal, so it hardly matters how stiff the metal is.»
«We realized that we could explain the data with what we call partial transmission processes, where metal phonons «feed» a much higher frequency diamond phonon at the interface.
