Cu1 Au3
semiconductor· Cu1 Au3
Cu1Au3 is an intermetallic compound composed of copper and gold in a 1:3 atomic ratio, classified as a semiconductor material. This compound belongs to the family of noble metal intermetallics and is primarily of research interest for studying electronic, optical, and catalytic properties in gold-copper systems. The material is not widely deployed in volume production, but represents an important composition point in the Cu-Au phase diagram for investigating how stoichiometric control affects bandgap, carrier mobility, and surface reactivity in precious-metal alloy systems.
