· JVASP-110951· ZnHgS2

ZnHgS₂ is a ternary sulfide ceramic compound combining zinc, mercury, and sulfur—a member of the chalcogenide family studied primarily in semiconductor and photonic research contexts. This material has attracted attention in optoelectronic research and radiation detection applications due to its wide bandgap and high atomic number (from mercury), making it potentially useful for UV-visible optical windows and gamma-ray scintillation or detection. While not yet widely deployed in mainstream industrial production, ZnHgS₂ represents an experimental composition in the broader space of II-VI semiconductors where researchers seek improved performance over conventional alternatives like CdTe or ZnSe, though practical challenges related to mercury volatility and material stability have limited commercialization.
