Determination of the thermoelectric efficiency of thermoelectric materials from measurements of linear series of branches for n- and p-types of conductivity

Resumo

The Harman approach is used to develop a method and derive formulas for simultaneous determination of the thermoelectric efficiency for materials with n- or p-type of conductivity. The data for calculation are obtained from measurements of the voltage drop arising when direct and alternating current are consecutively passed through linear assemblies consisting of an odd number of branches of both types of conductivity.
