  • MgS solar-blind UV radiation detector
    Patent number: 8592935
    Abstract: A UV detector is designed to provide a photoresponse with a cutoff wavelength below a predetermined wavelength. The detector uses a sensor element having an active layer comprising a MgS component grown directly on a substrate. A thin layer metal layer is deposited over the active layer and forms a transparent Schottky metal layer.
    Type: Grant

  • ZnMgS-based UV detectors
    Publication number: 20030020021
    Abstract: The present invention relates to UV detectors comprising undoped Zn1-xMgxS as the UV responsive active material. Where x exceeds 0.3 the thickness of the active material must be below a critical value, for example if 0.30<x<1.00, and the active material is formed as a layer of a thickness t wherein 5000 Å≧t≧100 Å. A particularly preferred combination of x and thickness is x=0.57 and t≦1400 Å because at around these values the UV response of the active material is similar to the UV response of human skin.

  • Visible-blind UV detectors
    Patent number: 6362483
    Abstract: Visible-blind UV detectors are disclosed comprising an active layer of ZnSTe alloy. The Te composition can be varied to provide good lattice matching depending on the nature of the substrate (eg Si, GaP or GaAs) and a novel structure is provided to give high quantum efficiency. The invention also discloses UV detectors with an active layer of pure ZnS and with an active layer of ZnSSe.
