Abstract
- Inspired by recent research results that have demonstrated appealing thermoelectric performance of A-site cation-deficient titanates, this work focuses on detailed analysis of the changes in performance promoted by altering the defect chemistry mechanisms. The series of cation-stoichiometric SrTi1-xTaxO3 +/-delta and A-site deficient Sr1-x/2Ti1-xTaxO3-delta compositions (0.05
