Tunable High T, Superconducting Infrared Detectors. Phase 1

Abstract

This program is aimed at the development of superconductor based infrared detector in which sensitivity is optimized through control over composition and microstructure. Cation composition and thin film morphology are to be determined precisely in the thin film deposition process. The superconducting thin film is to have an oriented polycrystalline microstructure to achieve Josephson junction behavior directly through the anisotropic superconducting properties of YBa2Cu3O7-x. The deposition substrate will be an oxygen ion conductor to permit continuous and controlled adjustment of the superconductor's oxygen stoichiometry. Since the properties of the new oxide superconductors are so dependent on the oxygen stoichiometry of the crystal lattice, such a device can be tuned for various operating conditions.
