The Effect of Severe Plastic Deformation on Thermoelectric Performance of Skutterudites, Half-Heuslers and Bi-Tellurides
Year: 2019
Type: article
Abstract: Although thermoelectric materials with a figure of merit, ZT, higher than 1.2 have gained considerable interest in electric power generation, little is hitherto known on the influence of severe plastic deformation on thermoelectric performance. Severe plastic deformation is one of the elegant techniques to furnish ultrafine grained microstructure with a high level of point, linear and surface defects. Particularly the phonon scattering on these defects is used as a main route to reduce thermal conductivity in thermoelectric materials and - as a consequence - increasing ZT.
