Research Abstract

For the application to the thermoelectric device, layered metal oxide bulk ceramics were prepared by the spark plasma sintering method with fine metal oxide powders prepared using metal-organic compound decomposition method. Theoretical Seebeck coefficients of the Y doped SrTiO_3 and Sr_2TiO_4 were calculated by the first principles method. The results were compared with the experimental ones. Finally, we presented the fabrication of the high performance thermoelectric module.
