Thermoelectric materials have shown promise as a clean energy alternative to fossil fuels that can convert waste heat into electrical power. The Kauzlarich lab (He et al., Chem. Mater., 2019), in collaboration with Prof. Donadio and NASA-JPL, have been able to elucidate the structural and physical properties of a new material, Yb₂₁Mn₄Sb₁₈, showing large thermoelectric efficiency in the mid-to-high temperature regime. The favorable properties of Yb₂₁Mn₄Sb₁₈ come intrinsically from its unique crystal structure, highlighted below.
