熱電変換素子とその製造方法
Document Type and Number:
Japanese Patent JP6519230
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To achieve higher output of a thermoelectric conversion element.SOLUTION: In a thermoelectric conversion element, a magnetic substance layer 502 exhibiting a spin-Seebeck effect and a metal layer 503 exhibiting an inverse spin hole effect are laminated on a substrate 501. The magnetic substance layer 502 has larger spin current rush efficiency in a region on the substrate 501 side in comparison with the region on the metal layer 503 side, and the region on the metal layer 503 side has larger spin current rush efficiency in comparison with the region on the substrate 501 side. In the magnetic substance layer 502, a magnetic material composition continuously changes between the substrate 501 and the metal layer 503.SELECTED DRAWING: Figure 1
