摘要： An infrared sensor includes: a base substrate; a bolometer infrared receiver; a first beam; and a second beam. Each of the first and second beams has a connection portion connected to the base substrate and/or a member on the base substrate and a separated portion away from the base substrate, and is physically joined to the infrared receiver at the separated portion. The infrared receiver is supported by the first and second beams to be away from the base substrate. The infrared receiver includes a resistance change portion including a resistance change material the electrical resistance of which changes with temperature. The resistance change portion includes an amorphous semiconductor, and the first and second beams include a crystalline semiconductor made of the same base material as the resistance change material, and is electrically connected to the resistance change portion at the separated portion.

摘要： A gas sensor includes a substrate, a support layer, a base layer, a heater layer disposed on or above the base layer, a gas sensing layer that is disposed on or above one of the heater layer and the base layer and that has a gas concentration dependent electrical impedance, and a detection electrode that is electrically connected to the gas sensing layer and that detects the impedance of the gas sensing layer. The substrate has a cavity and an opening formed by the cavity. The support layer is disposed on the substrate so as to cover at least an entire periphery of the opening. The base layer is supported by the support layer above the cavity so as to be separated from the substrate. A portion of the support layer in contact with the cavity has a first phononic crystal structure structured by a plurality of regularly arranged through-holes.

摘要： A thermoelectric conversion element includes a p-type thermoelectric converter, an n-type thermoelectric converter, a first electrode, a second electrode, and a third electrode. One end of the p-type converter is electrically connected to one end of the n-type converter. The other end of the p-type converter is electrically connected to the second electrode, and the other end of the n-type converter is electrically connected to the third electrode. The p-type converter includes a first phononic crystal layer having a first phononic crystal structure including regularly arranged first through holes. The n-type converter includes a second phononic crystal layer having a second phononic crystal structure including regularly arranged second through holes. The through direction of the first through holes is a direction extending between the ends of the p-type converter. The through direction of the second through holes is a direction extending between the ends of the n-type converter.

摘要： An infrared sensor is formed in such a manner that an infrared receiver and a base substrate are spaced with a beam made of a thin-film phononic crystal in which through holes are arranged periodically. The beam made of a phononic crystal is formed in such a manner that a period P of through holes increases at arbitrary intervals in a direction from the infrared receiver toward the base substrate.
