Experimental conditions required for accurate measurements of electrical resistivity, thermal conductivity, and dimensionless figure of merit (ZT) using Harman and impedance spectroscopy methods
Beltrán-Pitarch, Braulio; Prado-Gonjal, Jesus; Powell, Anthony V.; García-Cañadas, Jorge AIP Publishing (2019-01-11)The Harman method is used extensively for the characterization of the dimensionless figure of merit ZT of thermoelectric (TE) materials and devices. However, its accuracy has often been questioned, since in many cases there ...
