Abstract
It is well known that in a wide variety of amorphous materials an empirical correlation exists between the plateau in the thermal conductivity κ and the bump in C/T3 where C is the specific heat [1,2]. Both occur at roughly the same temperature for a given material and this temperature lies between 3K and 10K. Recent theoretical efforts to explain the thermal conductivity have included fractons [3] and phonon localization [4,5]. It is not obvious, however, in the first case how one can map a glass onto a self-similar percolating network, or in the second case how one can explain the rise in κ above the plateau.KeywordsThermal ConductivityLocal ModeEmpirical CorrelationPhonon ScatteringResonant ScatteringThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
