Abstract
A SUPERSONDUCTOR BASED INFRARED DETECTOR WITH A CONTINUOUSLY VARIABLE SENSITIVITY IS PROPOSED. THE SUPERCONDUCTING THIN FILM IS TO HAVE A POLYCRYSTALLINE NATURE TO ACHIEVE JOSEPHSON JUNCTION BEHAVIOR DIRECTLY THROUGH THE ANISOTROPIC SUPERCONDUCTING PROPERTIES OF YBA(2)CU(3)O(7-X). THE DEPOSITION SUBSTRATE IS TO BE AN OXYGEN ION CONDUCTOR THAT WILL PERMIT CONTINUOUS AND CONTROLLED ADJUSTMENT OF THE SUPERCONDUCTOR'S OXYGEN STOICHIOMETRY. BECAUSE SUCH A DEVICE CAN BE TUNED FOR VARIOUS OPERATING CONDITIONS, THE LIMITATIONS PLACED ON PREVIOUS SUPERCONDUCTING INFRARED DETECTORS, SUCH AS THE NEED FOR DEMANDING TEMPERATURE CONTROL DURING OPERATION, WILL BE CIRCUMVENTED. PHASE I WILL BE CONCERNED WITH DEFINING FILM DEPOSITION CONDITIONS AND DETERMINING THE INFRARED CHARACTERISTICS OF THE SUPERCONDUCTING FILMS ON THE CHOSEN SUBSTRATE.
