Abstract

Eu_5.08Al₃Sb₆ can be described as a pseudo rock salt-like “(Eu/Al₄)Sb” structure. The polycrystalline synthesis of Eu_5+xAl_3+ySb₆ was optimized. The compositions exhibit n-type transport behavior, ultra-low thermal conductivity, and a high Seebeck coefficient. Eu_5.08Al₄Sb₆ shows a promising zT of 0.8 at a temperature of 873 K.
