LAMINATE STRUCTURE FOR THERMOELECTRIC CONVERSION, THERMOELECTRIC CONVERSION ELEMENT, INFRARED SENSOR AND METHOD FOR MANUFACTURING THE LAMINATE STRUCTURE FOR THERMOELECTRIC CONVERSION

摘要

PROBLEM TO BE SOLVED: To provide: a laminate structure for thermoelectric conversion, capable of preventing a thermoelectric material layer from peeling from a substrate in a manufacturing step by achieving high bondability between the thermoelectric material layer and the substrate, and maintaining thermoelectric characteristics in a direction horizontal to the substrate; a thermoelectric conversion element using the laminate structure for thermoelectric conversion; an infrared sensor manufactured using the thermoelectric conversion element; and a method for manufacturing the laminate structure for thermoelectric conversion.SOLUTION: The laminate structure for thermoelectric conversion has a structure in which a substrate 10, a buffer layer 20 formed by distributingly laminating a plurality of independent laminate portions 21 comprising Ti metal or Ti alloy, and a thermoelectric material layer 30 containing as effective components one or two elements selected from a first group of Bi and Sb and one or two elements selected from a second group of Te and Se are laminated in this order.
