Abstract

New apparatus for evaluation of the figure of merit (ZT) of thermoelectric devices has been developed. ZT value is comprised of three physical quantities, Seebeck coefficient, electrical conductivity, and thermal conductivity. We have already reported ZT evaluation system working from -10 °C to 150 °C. In this study, we present new apparatus for evaluating the ZT value of devices between 150 °C and 700 °C by direct measurement of thermal conductivity using guarded hot plate method.
