摘要: A linear temperature dependence of the specific heat in amorphous solids at very low temperatures is shown to follow from an ionic tunneling model. Moreover, this model predicts both observed and magnitude thermal conductivity also explains anomalous results obtained for phonon free path by means stimulated Brillouin scattering.
