Abstract: A thermoelectric device includes active elements containing thermoelectric materials of silicon, an alloy of silicon, a metal-silicide or silicon composite and an interconnection zone consisting of a metal interconnect and a re-crystallized phase consisting of material from the active thermoelectric elements. The metal interconnect is from a metal that does not form metal silicides in a solid state, has a certain solubility for components of the thermoelectric elements in the liquid phase and a low solubility of these components in the solid phase. The active thermoelectric elements are shaped with a first and a second contact interface. The interconnection between the different thermoelectric elements consists of at least two phases of material, one of which is mainly the metallic interconnection material, the other is formed by the re-crystallized components of the thermoelectric materials.

Abstract: Integrated thermal sensor having a housing delimiting an internal space. A support region extends through the internal space; a plurality of thermocouple elements are carried by the support region and are electrically coupled to each other. Each thermocouple element is formed by a first and a second thermoelectrically active region of a first and, respectively, a second thermoelectrically active material, the first thermoelectrically active material having a first Seeback coefficient, the second thermoelectrically active material having a second Seeback coefficient, other than the first Seeback coefficient. At least one of the first and second thermoelectrically active regions is a silicon-based material. The first and second thermoelectrically active regions of each thermocouple element are formed by respective elongated regions extending at a mutual distance into the internal space of the housing, from and transversely to the support region.

Abstract: A magnesium-based thermoelectric conversion material includes a first layer formed of Mg2Si and a second layer formed of Mg2SixSn1-x (here, x is equal to or greater than 0 and less than 1), in which the first layer and the second layer are directly joined to each other, and within a junction surface with the first layer and in the vicinity of the junction surface, the second layer has a tin concentration transition region in which a tin concentration increases as a distance from the junction surface increases. The junction layer is regarded as a site in which a tin concentration is found to be equal to or lower than a detection limit by the measurement performed using EDX.
