Thermoelectric Performance of Yttrium-substituted (ZnO)5In2O3Improved through Ceramic Texturing

Year: 2002

Type: article

Abstract: Thermoelectric oxides with comparatively high figures of merit possess layered structures. Because they exhibit thermoelectric anisotropy, textured crystal-axis-oriented ceramics should be produced in order to realize the best performance. We have succeeded in fabricating textured ceramics of yttrium-substituted (ZnO) 5 In 2 O 3 by the reactive templated grain growth (RTGG) technique, and achieved the highest figure of merit ( ZT ∼0.33 at 1073 K) among n-type oxide materials reported so far.
