· JVASP-155382· Cu2HgTeS4

Cu2HgTeS4 is a quaternary chalcogenide compound containing copper, mercury, tellurium, and sulfur—a material class typically studied for semiconductor and photovoltaic applications. This is primarily a research compound rather than an established industrial material; quaternary metal chalcogenides are investigated for their potential in solar cells, radiation detection, and infrared optics where tunable bandgaps and high absorption coefficients offer advantages over conventional semiconductors. The inclusion of mercury and tellurium makes this compound notable for specialized optoelectronic functions, though commercial adoption remains limited due to processing challenges and the toxicity concerns associated with mercury-containing systems.
