The power of aluminum: optimizing thermoelectric properties of the intermetallic, Eu<sub>5+<i>x</i></sub>Al<sub>3+<i>y</i></sub>Sb<sub>6</sub>
Eu<sub>5.08</sub>Al<sub>3</sub>Sb<sub>6</sub> can be described as a pseudo rock salt-like "(Eu/Al<sub>4</sub>)Sb" structure. The polycrystalline synthesis of Eu<sub>5+<i>x</i></sub>Al<sub>3+<i>y</i></sub>Sb<sub>6</sub> was optimized. The compositions exhibit n-type transport behavior, ultra-low thermal conductivity, and a high Seebeck coefficient. Eu<sub>5.08</sub>Al<sub>4</sub>Sb<sub>6</sub> shows a promising <i>zT</i> of 0.8 at a temperature of 873 K.
