Enhancing thermoelectric performance of CaMnO3 through a Y- and La- dual-doping strategy 2024 Access copy available to the general public Unrestricted A classical ceramic route has been used in this work to prepare Y and La co-doped CaMnO3 thermoelectric compound seeking to improve its thermoelectric properties. The study highlights significant improvements in electrical and thermal transport properties achieved with minimal doping levels and a cost-effective synthesis process. The co-doping strategy effectively reduced electrical resistivity (reaching 10.8 mΩ cm at 800 °C for 0.03 (Y, La)-doped samples) while maintaining a relatively high Seebeck coefficient (300 μV/K at 800 °C for 0.01 (Y, La)-doped samples). Moreover, the thermal conductivity was minimized (1.65 W/(K m) at 800 °C for 0.03 (Y, La)-doped samples), leading to outstanding thermoelectric performance, with 0.47 mW/(K2m) power factor, and 0.25 ZT values at 800 °C (for 0.01 (Y, La)-doped samples. These results are among the best values reported so far for this family of compounds, underscoring the potential of this material for high-temperature thermoelectric applications and the efficiency of the classical ceramic approach with reduced dopant usage. info:eu-repo/grantAgreement/ES/AEI/CEX2023-001286-S info:eu-repo/grantAgreement/ES/DGA/T54-23R info:eu-repo/grantAgreement/ES/UZ/UZ2022-IAR-09 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 5.6 2024 MATERIALS SCIENCE, CERAMICS 3 / 34 = 0.088 2024 Q1 T1 1.034 2024 Ceramics and Composites 2024 Q1 Electronic, Optical and Magnetic Materials 2024 Q1 Surfaces, Coatings and Films 2024 Q1 Process Chemistry and Technology 2024 Q1 Materials Chemistry 2024 Q1 9.1 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Madre, M.A. Universidad de Zaragoza (orcid)0000-0002-0794-3998 Dura, O.J.
