Search for the minimum thermal conductivity in mixed cryocrystals (CH₄)₁₋ξ Krξ
The isochoric thermal conductivity of (CH4)1-ξ Krξ solid solutions is studied between 40 K and ~ 150 K over the wide range of concentrations (ξ = 0.013, 0.032, 0.07, 0.115, 0.34, 0.71, 0.855, 0.937, and 0.97). A gradual transition from the thermal conductivity of a highly perfect...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The isochoric thermal conductivity of (CH4)1-ξ Krξ solid solutions is studied between 40 K and ~ 150 K
over the wide range of concentrations (ξ = 0.013, 0.032, 0.07, 0.115, 0.34, 0.71, 0.855,
0.937, and 0.97). A gradual transition from the thermal conductivity of a highly perfect
crystal to the minimum thermal conductivity is observed as the crystal becomes increasingly
more disordered. A qualitative description is given in the framework of Debye model of
thermal conductivity, which takes into consideration the fact that phonon mean free path
cannot decrease indefinitely.
