| Research Abstract |
The scientific basis for nano-welding, where the contacting portion of two thin metallic wires are melted with Joule heat and two wires are joined together, has been established. From the structural, electrical and mechanical characterizations of the Joule heat welds, it was found that the welding process was low-damage and the welds were the equal of the base metal in quality. Furthermore, functional, nano-thermoelectric devices utilizing the Seebeck effect around the dissimilar metal welds, i. e., very thin thermocouple and the circuit for nano-generator, were realized for future applications.
