(abstract)

In this study, we conducted experimental screening of 90 compositions expected to form DHH/THH compounds using liquid phase synthesis for high-throughput experiments. From this screening, two compositions, MgV2Co3Sb3 and Mg2NbNi3Sb3, were selected and synthesized as bulk materials to measure their thermoelectric properties. Both compositions demonstrated low thermal conductivity typical of half Heusler compounds, with MgV2Co3Sb3 showing the highest thermoelectric performance with a zT > 0.7 at 973 K as a triple half Heusler composition.
