Abstract:
1. A method for fabricating a thermoelectric device comprising: forming a first electrode having a top surface; depositing first interlayer materials on the top surface of the first electrode; forming a separating plate substantially vertical to the top surface of the first electrode to divide space over the first interlayer materials into a plurality of parts; whrein the separating plate comprises metals selected from Ni, Ag, Cu, Ti, Al, or comprises alloys of two or more metals thereof; depositing powder of the first thermoelectric materials in some parts and on a first top surface of the first interlayer materials, and depositing powder of the second thermoelectric materials in other parts and on a second top surface of the first interlayer materials, so as to form a stacked layer; sintering the powder to form at least one first thermoelectric element and at least one second thermoelectric element from the first thermoelectric materials and the second thermoelectric materials, and electrically connecting the first electrode with the first thermoelectric element and the second thermoelectric element, to form an integral module; and removing the separating plate from the integral module to form a thermoelectric device.
