The fabricating includes forming structures by depositing thin-film metal-semiconductor multilayers on substrates and depositing metal layers on the multilayers, joining metal bonding layers to form dual structures with combined bonding layers; and removing at least one of the substrates; and using the dual structure to form a thermoelectric segments. The method can include dicing the dual structures before or after removing the substrates. The method can include depositing additional bonding layers and joining dual structures to make thermoelectric segments of different thicknesses. Each multilayer can be about 5-10 ?m thick. Each bonding layer can be about 1-2 ?m thick. The bonding layers can be made of a material having high thermal and electrical conductivity. The multilayers can be (Hf,Zr,Ti,W)N/(Sc,Y,La,Ga,In,Al)N superlattice layers. Metal nitride layers can be deposited between each of the bonding layers and multilayers.Type: GrantFiled: November 30, 2010Date of Patent: June 17, 2014Assignee: Purdue Research FoundationInventors: Jeremy Leroy Schroeder, Timothy David Sands

Patent number: 8704077Abstract: A heat recycling system for recycling heat from an electronic device includes a pipe with an inside tube and an outside tube coiled around the inside tube. The inside tube is connected to a first airduct to receive heated air from the electronic device. The outside tube is to receive cooling air from outside. A number of thermoelectric modules are formed in walls of the inside tube. A first end of each thermoelectric module is inserted into the outside tube, and a second end of each thermoelectric module is inserted into the inside tube. Therefore, the number of thermoelectric modules may generate current.Type: GrantFiled: August 28, 2009Date of Patent: April 22, 2014Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Zh-Wei Jian
