Outline of Final Research Achievements |
Nanostructures were formed in oxide thermoelectric material using biological nanofabrication process in order to improve a thermoelectric properties. The electrical conductivity increased and the Seebeck coefficient deacreased due to introduced nanoparticles. As a result, the power factor of nanocomposite a-InGaZnO film was about three times larger than that of a-InGaZnO thin film. The increment did not strongly depend on the materials of nanoparticle. Additionally, the sample with a higher nanoparticles density shows a higher thermoelectric power factor. This result indicates that the increment of electrical conductivity was mainly formed by the defects at the interface of InGaZnO/nanoparticles. Finally, a transparent thermoelectric device was demonstrated using a-InGaZnO and ITO electrode.
