Abstract

Thermoelectric properties of several oxides were investigated. Al₂O_3-,TiO_2- or ZrO_2-doped ZnO showed large power factor over the wide temperature range. Fe₂O₃ showed large power factor by doping of TiO₂. BaO-doped RuO₂, BaRuO₃ and CaRuO₃ showed large power factor at high temperature. Improvement of electrical conductivity by doping was effective to increase power factor in these oxide materials.
