Physio-Chemical Factors Contributing to Thermoelectric Phenomena. Part 1: Thomson Heat in Metallic Systems

Abstract

The fundamental concepts of the Thomson heat and the basic equations governing the heat flows associated with its generation are presented. From considerations of these equations, two new techniques for measuring the Thomson coefficient have been developed and examined experimentally. The two new techniques of studying a sample subjected to thermal and electrical gradients, included a non-equilibrium approach, in which the initial rate of change of temperature within the sample leads to a value of the Thomson coefficient, and a method based on equilibrium considerations. The results obtained with these two new techniques agree reasonably well with the data obtained utilizing the standard technique and data extrapolated into this temperature range from previous work.
