Au1 Cu4 Er1
semiconductor· Au1 Cu4 Er1
Au1Cu4Er1 is an intermetallic compound combining gold, copper, and erbium in a 1:4:1 atomic ratio, belonging to the rare-earth-transition-metal alloy family. This material is primarily of research and exploratory interest rather than established commercial production, with potential applications in high-temperature structural materials, electronic packaging, or magnetoelectronic devices that exploit the combined properties of noble metals, base-transition metals, and rare-earth elements. The erbium addition typically enhances high-temperature stability and may enable specialized magnetic or electronic functionality compared to binary Au-Cu systems.
