Rezumat | ||||||
The temperature and volume dependences of the thermal conductivity of solid CHCl3
are described in the framework of a model, where the heat is transferred by phonons and
above the phonon mobility edge by “diffusive” modes migrating randomly from site to site.
The mobility edge ωo is determined from the condition, that the phonon mean free path restricted by the Umklapp processes cannot become smaller than half the phonon wavelength.
Significant deviations from the dependence Λ∝1/T are explained by the thermal conductivity
approaching its lower limit. |
