The electronic transport properties of liquid Ag - Te

We have systematically measured the conductivity and the thermopower of the Ag - Te system for concentrations in the neighbourhood of . Our ability to stir the sample while taking measurements has allowed us to accurately study the immiscible region below 31 at.% Te and to measure the complete extent of the p - n transition in the thermopower as stoichiometry is crossed. Our results are compared to the recent experimental results of Ohno et al [1], and are found to be largely in excellent agreement for thermopower and conductivity; however, in our data approximately at stoichiometry, a previously unseen feature in the conductivity is observed, and a significant deviation from the thermopower data of Ohno et al is also seen. This conductivity feature is consistent with, but much smaller than, peaks that have been observed in the conductivities in liquid and . We also include data for and dS/dT that have not been previously available. Our results are discussed in terms of the Kubo - Greenwood equations, and are compared to the highly unusual systems Ag - Se and Ag - S.
