Thermoelectric properties of electron doped SrO (SrTiO3) n (n= 1, 2) ceramics
Crystal structure and thermoelectric properties of Nb 5+-and Ln 3+-(rare earth: La 3+, Nd
3+, Sm 3+, and Gd 3+) doped SrO (SrTiO 3) n (n= 1, 2) ceramics, which were fabricated
by conventional hot-pressing, were measured to clarify the effects of Ti 4+-and Sr 2+-site
substitution on the thermoelectric properties. The thermal conductivities are very close
between the n= 1 and 2 phases either doped with Nb 5+ or Ln 3+ and decreased by∼ 60%
at room temperature and∼ 30% at 1000 K as compared to that of SrTiO 3, which is likely …
