Outline of Final Research Achievements

In this study, we propose a new stacked π-type structure sandwiched between an insulating layer using a metal direct bonding technology. By using this technique, significantly lowered layered structure the electrical resistance of the joint portion, because it can be produced by laminating at least one hundred sheets at a time, even when using a metal material having low Seebeck effect, a sufficiently practical level. And by utilizing the anodic oxide film formed on the aluminum surface as an insulating layer, to prepare an accordion structure device adhered by the bonding portion of the π-type structure. With such a structure, increasing the cooling performance, the structure itself can correspond to the shape of the heat source has a flexibility.
