Thermoelectric power and thermal conductivity in the silver-gold alloy system from 3-300°K

Abstract

The thermal conductivity, thermoelectric power and electrical resistivity for a series of 20 annealed polycrystalline Ag—Au alloys, covering the whole 100% α-solid solution range of the system, have been measured from 3° to 300°k. The thermoelectric power has been separated into diffusion and phonon drag components and the effect of Fe impurities has been taken into account. The attenuation of the phonon drag peak on alloying cannot be explained simply by the corresponding attenuation of the lattice component of the thermal conductivity, nor does it show the resurgence at high solute concentrations previously observed in other noble metal alloy systems.
