 Abstract: We report thermal conductivity measurements of a Pb0.9Cu0.1 film before (amorphous) and after (crystalline) annealing. Below Tc, where electronic effects are negligible, we found that the phonon contribution in the amorphous phase kamph was much larger than that in the crystalline phase. We also found that the temperature dependence of kamph resembles that of amorphous dielectrics, thus providing evidence that this sort of "glassy" behavior does not require the presence of covalent bonds.
