Outline of Final Research Achievements

At present, oxide-based thermoelectric materials are attracting attention as environmentally friendly materials that are composed of elements rich in resources and low toxicity, and are relatively stable even under high temperature and oxidizing environments. However, for oxide-based thermoelectric materials, showing the same matrix phase or the same crystal structure and high performance have not been found yet. Therefore, this research clarified , in particular, the thermoelectric characteristic of polycrystalline samples Pr1-xSrxMnO3 (0.1≦x≦0.7), La1-xSrxFeO3 (0.1≦x≦0.3), Pr0.9Sr0.1(Mn1-xFex)O3 (0≦x≦1), Pr1-xSrxFeO3 (0.1≦x≦0.7), and Pr1-xCaxFeO3 (0.1≦x≦0.9), and verified the possibility of the application to a thermoelectric conversion element.

Academic Significance and Societal Importance of the Research Achievements

本研究は、Fe3+のスピン状態を制御し中間スピンFe3+が多数を占めるペロブスカイトFe酸化物に着目し、多結晶試料を作製して、そのp型或いはn型熱電特性を明らかにすることが重要であるという知見を得た。この研究によって、p型及びn型の高い性能を示すペロブスカイトFe酸化物が発見されれば、高温・酸化環境下での熱電発電のエネルギー変換効率向上に貢献するだけでなく、喫緊の課題である持続可能社会の促進をもたらす材料の実用化に新しい展開が期待される。
