  • Publication number: 20190165199
    Abstract: A UV radiation detector includes: a diode including a substrate having a first side and a second side, the first side and the second side being located on opposing faces of the substrate, an active layer including rocksalt phase crystalline structure CaS disposed on the first side of the substrate, an electrical contact disposed on the second side of the substrate, and a semi-transparent conducting layer disposed on the active layer; and a circuit connecting the semi-transparent conducting layer and the electrical contact. The UV radiation detector detects radiation having a wavelength between 200 and 280 nm.

  • Publication number: 20180198015
    Abstract: A diode, UV radiation detector, and method of manufacturing semiconductor device that includes a diode with a substrate having a first side and a second side. The diode includes an active layer having a rocksalt phase crystalline structure of CaS disposed on the first side of the substrate, and an electrical contact disposed on the second side of the substrate. The diode also includes a semi-transparent conducting layer disposed on the active layer. The UV radiation detector includes the diode and circuitry connecting the semi-transparent conducting layer and the electrical contact. The UV radiation detector may detect radiation having a wavelength between 220 and 280 nm. The substrate may have a lattice mismatch between 0.47% and 12.6% with respect to the active layer.
