Eu-Substituents-Induced Modifications in the Thermoelectric Properties of the Zintl Phase Ba_1-<i>x</i>Eu<i>_x</i>Zn₂Sb₂ System.

ABSTRACT: Four quaternary Zintl phase thermoelectric (TE) materials belonging to the Ba_1-xEu_xZn₂Sb₂ (x = 0.02(1), 0.04(1), 0.08(1), 0.15(1)) system were successfully synthesized using the molten Pb-flux or the conventional high-temperature reaction methods. Their crystal structures were characterized by both powder and single-crystal X-ray diffraction analyses, and all four isotypic title compounds adopted the orthorhombic BaCu₂S₂-type (Pnma, Z = 4, Pearson code oP20) structure. The radius ratio criterion, based on the cationic and anionic elements (i.e., r₊/r_-), was successfully verified in the title system, as in our previous reports, where r_+<
