Heat transfer in crystalline clathrate hydrates at low temperatures

The experimental results on the thermal conductivity k(T) of crystalline Xe, CH₄, and THF clathrate hydrates
 have been analyzed. In a wide region of temperatures above 2 K, k(T) exhibits a behavior typical of
 disordered solids, which depends weakly on their chemical composition, cr...

description The experimental results on the thermal conductivity k(T) of crystalline Xe, CH₄, and THF clathrate hydrates
 have been analyzed. In a wide region of temperatures above 2 K, k(T) exhibits a behavior typical of
 disordered solids, which depends weakly on their chemical composition, crystalline structure and microstructure.
 The results are discussed in the context of phenomenological models of phonon scattering by local
 modes. It has been found that the Xe clathrate has a feature unusual for glasses, namely, k(T) decreases almost
 two-fold as the temperature increases from 50–100 K. The behavior of k(T) is presumably determined
 mainly by the strong phonon scattering on water molecules.

The study was partially supported with a Grant of
 President of Ukraine for young scientists engaged in scientific
 research (GP/F13/0037). We thank Prof. Vadim Manzhelii, Prof. Werner Press,
 and Prof. Javier Bermejo for fruitful discuss.
