Ga4 Au4
semiconductor· Ga4 Au4
Ga₄Au₄ is an intermetallic compound combining gallium and gold in a 1:1 atomic ratio, belonging to the family of noble metal–semiconductor intermetallics. This material is primarily of research interest rather than established industrial production, investigated for potential applications in high-temperature electronics, photonics, and specialized semiconductor devices where the combination of gold's stability and gallium's semiconducting properties could offer unique functionality.
