Abstract

A thermoelectric device includes at least one first flow duct, at least one second flow duct, at least one first carrier layer associated with the at least one first flow duct and at least one second carrier layer associated with the at least one second flow duct, at least one intermediate space between the first carrier layer and the second carrier layer and a plurality of p and n-doped semiconductor elements disposed in the at least one intermediate space and electrically interconnected. A relative first thermal expansion of the first carrier layer and a relative second expansion of the second carrier layer are equal under operating conditions. Suitable materials are provided for the first and second carrier layers that promote the use of such thermoelectric devices in exhaust systems of a motor vehicle. A motor vehicle having thermoelectric devices and a method for manufacturing a thermoelectric device are also provided.
