  • Bulk semiconducting scintillator device for radiation detection
    Patent number: 9429662
    Abstract: A bulk semiconducting scintillator device, including: a Li-containing semiconductor compound of general composition Li-III-VI2, wherein III is a Group III element and VI is a Group VI element; wherein the Li-containing semiconductor compound is used in one or more of a first mode and a second mode, wherein: in the first mode, the Li-containing semiconductor compound is coupled to an electrical circuit under bias operable for measuring electron-hole pairs in the Li-containing semiconductor compound in the presence of neutrons and the Li-containing semiconductor compound is also coupled to current detection electronics operable for detecting a corresponding current in the Li-containing semiconductor compound; and, in the second mode, the Li-containing semiconductor compound is coupled to a photodetector operable for detecting photons generated in the Li-containing semiconductor compound in the presence of the neutrons.
    Type: Grant
    Filed: March 31, 2014
    Date of Patent: August 30, 2016
    Assignees: Consolidated Nuclear Security, LLC, Fisk University
    Inventors: Ashley C. Stowe, Arnold Burger, Michael Groza
  • Modification of solid state CdZnTe (CZT) radiation detectors with high sensitivity or high resolution operation
    Patent number: 8884228
    Abstract: An apparatus and process is provided to illustrate the manipulation of the internal electric field of CZT using multiple wavelength light illumination on the crystal surface at RT. The control of the internal electric field is shown through the polarization in the IR transmission image under illumination as a result of the Pockels effect.
