Comparison of Mercuric Iodide and Lead Iodide X-Ray Detectors for X-Ray Imaging Applications

Mercuric iodide (HgI 2 ) and lead iodide (PbI 2 ) materials have been investigated for several years as direct converter layers for digital x-ray imaging applications. A difficult challenge of both lead iodide and mercuric iodide is the higher than desired leakage currents. These currents are influe...
