AB - Dynamic measurement techniques such as ac resistivity and the Cahill 3- omega 1990 thermal conductivity method induce periodic currents in materials. In thermoelectric materials the coupling between electrical and thermal effects means the normal mode excitations are generally attenuated waves of mixed electrical/thermal character. Since ZT is one measure of the coupling between the electrical and thermal effects it is perhaps not surprising that ZT is also a measure of the mixing. This paper examines solutions to the coupled thermoelectric diffusion problem and discusses some implications for measurements. (4 References).
