· Cu2 Au2 Se8

Cu2Au2Se8 is a quaternary semiconductor compound combining copper, gold, and selenium in a fixed stoichiometric ratio. This material belongs to the family of mixed-metal chalcogenides and is primarily of research interest rather than established in high-volume industrial production. The compound is investigated for potential applications in thermoelectric energy conversion and photovoltaic devices, where the combination of elements offers tunable band gaps and carrier properties; it represents an emerging materials platform for exploring how alloying precious and base metals with chalcogenides can enhance performance in energy harvesting and conversion applications.
