Study of trapping in mercuric iodide by thermally stimulated current measurements

Abstract
Thermally stimulated current measurements have been performed in red mercuric iodide crystals grown by a vapor‐phase technique. They reveal the presence of a hole trap at Ev+0.45 eV with a capture cross section of 10−15 cm2. Two additional centers were found when the crystals were cleaved rather than etched.
