Synthesis and characterization of n-type and p-type thermoelectric oxides

Year: 2010

Type: article

Abstract: α and γ Al2O3 doped sintered ZnO (n-type) and sintered CuAlO2 (p-type) pellets were prepared by conventional solid state synthesis starting from the oxides. 2% γ Al2O3 doped ZnO was the best n-type sample showing a thermoelectric figure of merit ZT = 0.17 at 800℃. In the case of p-type CuAlO2 sample, ZT = 0.035 at 800℃ was obtained by application of melt-textured growth (MTG) process to the sintered pellet. In this work, MTG was recognized for the first time as effective way for the enhancement of thermoelectric properties of CuAlO2.
