Improved Thermoelectric Properties of SrTiO via (La, Dy and N) Co-Doping: DFT Approach.

This work considers the enhancement of the thermoelectric figure of merit, ZT, of SrTiO (STO) semiconductors by (La, Dy and N) co-doping. We have focused on SrTiO because it is a semiconductor with a high Seebeck coefficient compared to that of metals. It is expected that SrTiO can provide a high power factor, because the capability of converting heat into electricity is proportional to the Seebeck coefficient squared.
