· JVASP-116451· As2Au

As₂Au is an intermetallic compound combining arsenic and gold in a 2:1 stoichiometric ratio. This is a research-phase material within the gold-arsenic binary system, studied primarily for its potential in semiconductor, optoelectronic, and specialized electronic applications where the combination of gold's conductivity and chemical stability with arsenic's semiconducting properties may offer distinct advantages. The material remains largely experimental; its development is motivated by the need for novel compounds in high-frequency electronics and integrated circuit architectures, though practical production and integration challenges limit current industrial deployment.
