Ca2 Au4

semiconductor

· Ca2 Au4

Ca₂Au₄ is an intermetallic compound formed from calcium and gold, belonging to the class of metallic semiconductors or semimetals with mixed ionic-metallic bonding character. This is primarily a research material rather than an established commercial compound, studied for its electronic structure and potential in advanced materials science applications. The material represents an emerging area of intermetallic chemistry where gold's electronic properties are combined with calcium's reducing character, making it of interest to researchers exploring novel phases with tunable electrical or thermoelectric behavior.
