The peculiarities of heat transfer in CO₂ and N₂O solids at low temperatures
The thermal conductivities of CO₂ and N₂O solids have been investigated in the low-temperature range
 1–40 K. The thermal conductivities of CO₂ and N₂O are large compared with those of simple molecular crystals
 such as N₂, CO, or O₂ in the whole investigated temperature range. Analy...

| description | The thermal conductivities of CO₂ and N₂O solids have been investigated in the low-temperature range
1–40 K. The thermal conductivities of CO₂ and N₂O are large compared with those of simple molecular crystals
such as N₂, CO, or O₂ in the whole investigated temperature range. Analysis of the experimental data by
the Callaway method shows that relatively large size of crystalline grains, low density of dislocations and
weak phonon–phonon interaction might be the reasons for the good thermal conduction in these crystals at
temperatures near the maxima. A comparison between calculated values of the intensity of normal phonon
scattering processes and experiment gives evidence that in N₂O there is an additional (in comparison with
CO₂) giant scattering of phonons. This scattering is described in the frameworks of soft potential model by
the resonance phonon scattering on tunnel states and low-energy vibratons.
