  • Superconducting detector and method of making same
    Patent number: 5264375
    Abstract: A detector useful for detecting infrared (IR) radiation is described which is formed of an epitaxial film of superconductive material having a high transition temperature Tc. Specifically, an oxide of yttrium barium and copper is preferred for the high Tc material. The sensor is formed on a single crystalline silicon body suspended by a silicon nitride membrane over a gap formed in a silicon base body and thermally isolated thereby.
