  • Spectral Performance of Mercuric Iodide Gamma Ray Detectors at Elevated Temperatures
    with values ranging from 1012 to 1013 Ohm.cm. It can therefore sustain high bias voltages while still generating low leakage currents. In addition, the large atomic numbers of the constituent elements of mercuric iodide (mercury Z=80 and iodine Z=53) in conjunction with a high density of 6.3 g/cm3
  • Spectroscopy on Thick HgI2 Detectors: A Comparison Between Planar and Pixelated Electrodes
    electrodes are made of palladium. poor charge transportation characteristics. HgI2 has a wide. The area of each anode pixel is ~1 mm2 and the total area is. band-gap (2.1 eV), high atomic numbers (53 for iodine, 80 for. approximately 1 cm2. When the cathode is negatively biased,. mercury), and a high
  • Soluble Narrow Band Gap and Blue Propylenedioxythiophene-Cyanovinylene Polymers
