Abstract

Mercuric Iodide is a preferred candidate material for truly room-temperature radiation detectors because of its large electronic bandgap (2.1 eV) and the high atomic number of its constituent elements, which results in a high photopeak efficiency. The spectroscopic performance of the detectors is determined by the electronic transport properties of the material which depends on the purity and the structural homogeneity of the single crystals from which the detectors are fabricated. Recent advances in purification and crystal growth have made it possible to fabricate routinely large, stable gamma ray and X-ray detectors and counters.
