The effect of Ag + on the thermoelectric properties of Sm 3+ - and Ti 4+ - co-doped KSr 2 Nb 5 O 15 ceramics: a combined first-principles and experimental study on synergistic optimization of thermal and electrical transport
Source abstract
Abstract
Ag + doping in KSNST induces lattice anharmonicity and Umklapp scattering, and the point defects and oxygen vacancies act as effective phonon scatter centres, significantly reducing thermal conductivity, especially at high doping levels.
