Ca4 Al4 Au4
semiconductor· Ca4 Al4 Au4
Ca₄Al₄Au₄ is an intermetallic compound combining calcium, aluminum, and gold in a 1:1:1 stoichiometric ratio. This is an experimental research material in the semiconductor/intermetallic family, synthesized primarily for fundamental studies of ternary phase diagrams and electronic structure rather than established industrial production. The gold-containing composition suggests potential interest in high-reliability electronics or specialized photonic applications, though practical deployment remains at the research stage.
