Pivotal role of Sb vacancies in quaternary half-Heusler thermoelectrics
The pivotal role of intrinsic defects in nominally stoichiometric X(Fe 0.5 Ni 0.5 )Sb quaternary half-Heuslers (X = Ti, Zr, or Hf) is revealed. The Sb vacancies naturally occur during synthesis and can alter the conduction behavior from n-to p-type.
