Au1 Cu4 Yb1
semiconductor· Au1 Cu4 Yb1
Au₁Cu₄Yb₁ is an intermetallic compound combining gold, copper, and ytterbium in a 1:4:1 atomic ratio. This is a research-phase material rather than an established commercial alloy; intermetallic compounds of this type are studied for potential applications in thermoelectric devices, electronic components, and advanced functional materials where the combination of noble metals and rare-earth elements may offer favorable electronic or thermal transport properties.
