Complete Characterization of Thermoelectric Materials by Impedance Spectroscopy
Beltrán-Pitarch, Braulio; Prado-Gonjal, Jesus; Powell, Anthony V.; Martínez-Julián, Fernando; García-Cañadas, Jorge American Chemical Society (2019-05-01)Thermoelectric materials can directly convert waste heat into electricity. Because of the vast amount of energy available as waste heat in our society, these materials could contribute to reduce our dependence on fossil ... -
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 ... -
Fabrication and evaluation of a skutterudite-based thermoelectric module for high temperature applications
García-Cañadas, Jorge; Powell, Anthony V.; Kaltzoglou, Andreas; Vaqueiro, Paz; Min, Gao Springer (2013-07)We report a straightforward methodology for the fabrication of high-temperature thermoelectric (TE) modules using commercially available solder alloys and metal barriers. This methodology employs standard and accessible ... -
Thermal conductivity, electrical resistivity, and dimensionless figure of merit (ZT) determination of thermoelectric materials by impedance spectroscopy up to 250 °C
Beltrán-Pitarch, Braulio; Prado-Gonjal, Jesus; Powell, Anthony V.; Ziolkowski, Pawel; García-Cañadas, Jorge AIP Publishing (2018-07)Impedance spectroscopy has been shown as a promising method to characterize thermoelectric (TE) materials and devices. In particular, the possibility to determine the thermal conductivity λ, electrical conductivity σ, and ...
