| Outline of Final Research Achievements |
Inorganic nanostructured materials were precisely synthesized and their properties were characterized to study the contribution of inorganic nanostructures to the development of new inorganic thermoelectric materials. A dramatic increase in the thermoelectric property, by downsizing of Bi nanowires down to smaller than 10 nm, is theoretically expected. In this study we have succeeded in synthesizing Bi nanowires with 6 -9 nm in diameter. In addition, a large decrease in the thermal conductivity, owing to the presence of ordered mesopores, was observed for mesoporous Nb-doped TiO2. On the basis of these results we have clarified the critical role of precise synthesis of inorganic nanostructured materials on the study of the relationship between nanostructures and thermoelectric properties.
