Paper Abstract

Many materials used in radiation detectors are environmentally unstable and/or fragile. These properties are frustrating to researchers and add significantly to the time and cost of developing new detectors as well as to the cost of manufacturing products. The work presented here investigates the properties of HgS. This material was selected for study based partly on its inherent stability and ruggedness, high density, high atomic number, and bandgap. HgS is found in nature as the mineral cinnabar. A discussion of the physical properties of HgS, experimental characterization of natural cinnabar, and initial radiation detection results are presented along with a discussion of potential crystal growth techniques for producing crystals of HgS in the laboratory.
