Improvements in the thermoelectric efficiency of SrTiO3 through donor doping
Abstract
The SrTiO3 perovskites n-doped with Sm3+, Dy3+, and Nb5+ were prepared via the conventional solid state reaction route (SSR) followed by spark plasma sintering (SPS) process. The SPS in dynamic vacuum promotes formation of Ti3+ and Nb4+ species, as verified by the XPS analysis. Presence of the reduced cations, primarily Ti3+, is in agreement with the observed color changes and enhanced electrical conductivity of the samples. The Sr-site …
