· Hg6 As2

Hg₆As₂ is a mercury-arsenic binary compound belonging to the narrow class of mercury chalcogenide and pnictide semiconductors. This material is primarily of research and specialized device interest rather than high-volume production, explored for its unique electronic and optical properties in the mercury-based semiconductor family. Applications remain largely experimental, centered on infrared detection, specialized optoelectronic devices, and fundamental studies of mercury-pnictide phase behavior; its toxicity and rarity in production limit industrial adoption compared to mainstream III-V semiconductors or silicon.
