“…While previous reports of this material and its calcium analogues call it “10–1–9″, this is more of a nickname than a precise description of the stoichiometry of this material. Various X-ray refinements including those from single crystals for materials in this family suggest stoichiometries in the range of 10–11.01:0.35–1.38:9 due to suggested partial occupancies on the cation sites that may be compensated with additional Sb-bonding . Yb 10.5 MnSb 9 is a Zintl-balanced composition that has been suggested in work on the Mg analogue and is roughly an average stoichiometry for this material family .…”

The Yb−Mn−Sb phase space contains many different Zintl phases of interest for thermoelectric applications. While the Yb 11 Sb 10 phase was first reported and explored years ago, only recently was the Yb 10 MnSb 9 phase first reported. These phases have incredibly similar crystal structures and differ in composition only slightly. Despite these similarities, Yb 11 Sb 10 is reported to be metallic with poor thermoelectric performance, whereas Yb 10 MnSb 9 has been shown to be semiconducting, exhibiting decent thermoelectric properties. In this work, we consider how these phases are both similar and different through an investigation of the crystal structure, electronic band structure, and the experimental transport properties. We then consider how these properties evolve in a two-phase mixture. We show that the thermoelectric properties of samples with intermediate compositions between Yb 11 Sb 10 and Yb 10 MnSb 9 exhibit transport behavior that is well explained by an effective medium theory of a two-phase mixture. This study improves our understanding of the Yb−Mn− Sb phase space, which has major implications for other high-performing thermoelectric materials in the A-M-Sb space (A = Yb, Ca; M = Mn, Mg, Zn, Ga, and In) such as Yb 14 MnSb 11 .
