All compositions exhibit both an increase in absolute Seebeck coefficient and electrical resistivity with temperature. Moreover, compared to the Nb-substituted sample, the thermal conductivity of the W-substituted samples was strongly reduced. This reduction is attributed to the nearly two times greater mass of tungsten. Consequently, a ZT of 0.19 was found in CaMn0.97W0.03O3-δ at 1000 K, which was larger than ZT exhibited by the 2% Nb-doped sample. 000133279 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000133279 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000133279 700__ $$aEilertsen, James 000133279 700__ $$aThiel, Philipp 000133279 700__ $$0(orcid)0000-0002-1296-4793$$aAguirre, Myriam H$$uUniversidad de Zaragoza 000133279 700__ $$aOtal, Eugenio 000133279 700__ $$aPopuloh, Sascha 000133279 700__ $$aYoon, Songhak 000133279 700__ $$aWeidenkaff, Anke 000133279 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
