· ScAgSe2

ScAgSe2 is an intermetallic compound combining scandium, silver, and selenium, representing an emerging material in the family of ternary metal chalcogenides. This compound is primarily investigated in materials research rather than established in high-volume industrial production, with potential applications in semiconductor and thermoelectric device research where the unique electronic and thermal transport properties of mixed-metal selenides are exploited.
