| Outline of Final Research Achievements |
Regarding the Joule heat welding of fine scale dissimilar metals, a parameter which governs the melting phenomenon at the contacts of fine scale metals has been proposed, and the scientific basis for welding thin wires having different diameters or for welding thin wire to the substrate has been established. Moreover, the thermoelectric nanowires have been successfully fabricated by the use of atomic migration, and by gathering the above knowledge and achievements, a plate-type thermoelectric generator and the thermoelectric probes, which greatly contribute the future green innovation, have been realized.
