From synthesis to machine learning validation for the thermoelectric Zintl phase Ba 1− x Eu x Zn 2− y Al y Sb 2 system
Abstract
New Zintl phases in the Ba 1− x Eu x Zn 2− y Al y Sb 2 system were synthesized via a machine-learning validated approach. The Eu/Al co-substitution induces atomic disordering, suppressing κ tot to 0.24 W m −1 K −1 and yielding a ZT = 0.50 at 755 K.
