| Outline of Final Research Achievements |
In order to fabricate tilted-multilayer-type power modules based on the off-diagonal thermoelectric (ODTE) effect, wherein the electric current flows perpendicular to the temperature gradient, we performed computer simulation and designed several prototype modules. Consequently, we have confirmed the occurrence of the ODTE effect. The output power was proved to depend on the relative thickness of the TE material, as well as the tilted angle of the module and the highest power was demonstrated to occur at around the relative thickness of ~0.1 and the angle of ~30 degree. In the actually fabricated modules, diffusion of constituent elements was confirmed to deteriorate the output power. Nevertheless, the highest output power was higher than that obtained from the conventional pai-type TE modules.
