| Outline of Final Research Achievements |
In this research subject, we have performed the investigation of thermoelectric materials by utilizing the strong electric field that is induced at the solid liquid interface in electric double layer transistors. The purposes of this study are i) the control of the thermoelectric response by electric field and ii) the realization of the novel electronic states with high thermoelectric performance. In the fiscal year 2014, we established the method to control the Seebeck effect with the strong electric field on the electric double layer. In the fiscal years 2015-2016, we applied the established approach to various thermoelectric materials; specifically, oxide semiconductors such as SrTiO3 and ZnO, transition metal dichalcogenides, and single-walled carbon nanotubes were investigated. The results obtained through this study would lead to the development of the novel thermoelectric materials and to the thermoelectric device applications.
