Abstract: A photosensitive device includes an insulator base on which are located inner, outer and intermediate space electrodes which delineate concentric circular or noncircular areas which are occupied by a photoconductive material engaging opposing edges of the electrodes along their lengths. One or more of the electrodes may be open across their lengths, the openings being occupied by photoconductive material connecting adjacent areas. One or more of the electrodes may be provided with spaced parallel legs interdigitated by legs of another of the electrode.

Abstract: An infrared detector array is fabricated by alloying a slice of mercury doped germanium to a degenerate germanium substrate. After being lapped to the desired thickness, the slice is etched through to the substrate to form individual detector bars using a metal mask which is then partially removed to form a gold contact strip on each bar. Output conductors are formed by patterning copper films thermocompression bonded to high temperature plastics, gold plating the conductors, and connecting the gold plated conductors to the gold contact strips by gold jumper wires thermocompression bonded to the conductors and to the contact strips.

Abstract: High quantum yields are provided by sandwiching an insulating layer in contact with a photoconductor between two electrodes. The sandwiched structure in conjunction with an applied electrical potential and excitation light provides an electrical switching device. Optionally, an imaging layer can be included between the photoconductive layer and one of the electrodes, and can be imaged with increased sensitivity.

Abstract: There is disclosed apparatus for measuring precisely, to 0.01 C*, difference in temperature including thermistors, which are subject to the temperatures whose difference is being measured. The logarithm of electrical resistance of each thermistor is proportional to its temperature and the thermistors are connected in a ratiometric circuit for measuring their relative resistances. Each thermistor is a ceramic of ferroelectric material (for example, barium-strontium titanate) formed by mixing powders of different compositions, each composition having a different ferroelectric resistance anomaly, and then firing and oxidizing bodies pressed from the mixture of powders. The mixture of powders is heterogeneous so that the grains of the ceramic include a plurality of particles of powder which microscopically would manifest distinct ferroelectric resistance anomalies if fired alone but the macroscopic response of the ceramic is loglinear over a substantial temperature range.
