Abstract:
The thermal and electrical conductivities of two pure and six cadmium-doped single crystals of tin have been measured. The pure samples were analyzed with respect to the anisotropic transport properties of the tin system, whereas the alloy samples provided a determination of the lattice thermal conductivity and measured deviations from Matthiessens rule. The six cadmium-doped samples contained from 0.24 to 0.97 atomic percent impurity. The three most impure samples yielded an adequate measurement of the lattice thermal conductivity. These values were obtained by utilizing the pure measurements to determine the ideal thermal resistivity and by correcting the residual resistivity with the measured deviations from Matthiessens rule as suggested by Klemens. A suitable theoretical fit to these lattice conductivities was obtained by choosing approrpiate electron-phonon, point defect, and umklapp scattering terms.
