| Popis: | The temperature and volume dependences of the thermal conductivity of solid CHCl3 are analyzed within the Debye model, under supposition that the phonon mean free path is approximately equal to one half of the wavelength. A quantitative description is given under assumption that 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. |
