Exploring the high-temperature electrical performance of Ca3-xLaxCo4O9 thermoel...
Constantinescu, Gabriel; Rasekh, Shahed; Amirkhizi, Parisa; Lopes, Daniela V.; Vieira, Miguel A.; Kovalevsky, Andrei V.; Diez, Juan C.; Sotelo, AndresAliovalent substitutions in Ca3Co4O9 often result in complex effects on the electrical prop-erties and the solubility, and impact of the substituting cation also depends largely on the prepara-tion and processing method. It is also well-known that the monoclinic symmetry of this material’s composite crystal structure allows for a significant hole transfer from the rock salt-type Ca2CoO3 buffer layers to the hex...
