Good Agreement

In this study, the transport theorem of phonons and electrons is utilized to create a model to predict the thermal conductivity of composite materials. By observing or assuming the dopant displacement in the matrix, a physical model between dopant and matrix can be built, and the composite material can be divided into several regions. In each region, the phonon or electron scattering caused by boundaries, impurities, or U-processes was taken into account to calculate the thermal conductivity. The model is then used to predict the composite thermal conductivity for several composite materials. It shows a pretty good agreement with previous studies in literatures. Based on the model, some discussions about dopant size and volume fraction are also made.

Anisotropic Thermal Conductivity

AbstractThe thermal conductivities of superconducting, Sr-doped lanthanum copper oxide single crystals have been measured from room temperature to below 100 mK parallel and perpendicular to the copper oxide planes. While the results indicate that the heat conduction is strongly anisotropic, the data have been analyzed in terms of a modified Bardeen-Rickhayzen-Tewordt theory of lattice thermal conductivity. It is shown that while electron scattering plays an important role in limiting the in-plane heat conductivity, this scattering channel is masked by other mechanisms for heat transport across the planes.

Dilute Alloy

Low-temperature measurements of electrical resistivity, thermal conductivity, and thermoelectric power on silver alloys containing 0.005, 0.067, 0.11, and 0.31 at.% of manganese are reported. The same specimens were used for the measurement of all properties over the temperature range from 2 to 25 °K. The well-known minimum and maximum are observed in the electrical resistivity of the three more concentrated alloys and the minimum is visible in the most dilute alloy near the lowest temperatures of measurement. Associated effects are observed in the other properties and their possible relationship to theoretical electron scattering mechanisms, particularly that of Kondo, is discussed.

The electrical resistivity, thermal conductivity, and thermoelectric power of Rb have been measured between 40 and 300 K. Two of the samples were bare, to avoid thermal contraction difficulties; the softness of these samples necessitated further, calibration, measurements on a third sample in glass, just below the freezing point. The electrical resistivity values agree well with published values of Dugdale and Phillips. The Lorenz function, not previously examined in detail above 25 K, shows strong evidence of electron–electron scattering, of a strength intermediate to that calculated by Kukkonen for Thomas–Fermi screening, and for Geldart–Taylor screening. Such scattering appears to have affected the thermoelectric power as well.

Thermal Resistivity

The thermal conductivity, electrical resistivity, and thermoelectric power of Cs have been measured from 40 K, through the melting point which is near 300 K, up to 600 K. The thermal resistivity of both solid and liquid Cs contains a contribution from electron–electron scattering, which agrees well with theory. The electrical resistivity shows an appreciable "premelting" effect, which is tentatively attributed to impurities.
