“…To study this influence, it is necessary to elucidate the features of the interaction of phonons with the planar defect. The studies of resonance effects in the scattering of acoustic waves from and formation of localized and resonance vibrational states on a planar defect have a considerable interest [3][4][5][6][7][8][9], since such effects can give rise to the features in the kinetic phonon characteristics of the intercrystalline interfaces which can be experimentally observed.…”

The different mechanisms of resonant transport of phonons between two media in the presence of impurity intermediate layer are described. Particular attention is focused on the resonance interaction of elastic waves with a two-dimensional defect on the contact boundary between two solids, on the multichannel interface phonon scattering and on the experimentally observed nonmonotonic temperature dependence of the reduced heat flux. In the cases when there is a direct interaction between edge atoms of the matrix as non-nearest neighbors or when the impurities do not fill completely the 2D interface layer, the additional channel for the transmission of phonons through the interface opens. This additional transmission channel manifests itself as a transmission (or reflection or absorption) peak with an asymmetric line shape (the so-called Fano resonance for phonons due to interference between the two transmission channels). Some applications of the Fano effect in magnon heat conductivity are also discussed. PACS: 63.20.-e Phonons in crystal lattices.

“…These two states are separated from one another by an energy barrier and transitions between them are tunneling. Such a tunnel state (TLS) may influence the thermal conductivity of the structure by modification of the spectrum of the crystal lattice vibrations . A final decision whether the observed deflection is caused by the TLS or not could be made on the basis of a similar thermal conductivity experiment carried out on a ND 3 crystal, where the tunnel splitting of ammonia molecule features significantly lower energy .…”

The results of measurements of the thermal conductivity dependence on temperature of pure ammonia crystal obtained in the temperature range 1.3–44 K have been shown. Quantitatively, the sample displays the thermal conductivity typical for a dielectric crystal. Below 2 K a singularity of the dependence of thermal conductivity coefficient on temperature was observed. The singularity was linked to the existence of TLS in the crystal. The analysis of the temperature dependence of the phonon mean free path in the NH3 crystal was also done.
