Al1 Sc1 Au2

Al₁Sc₁Au₂ is an intermetallic compound combining aluminum, scandium, and gold in a defined stoichiometric ratio, classified as a semiconductor. This is a research-phase material rather than a commercial alloy; such ternary intermetallics are studied for potential electronic and optoelectronic applications where the combination of a light metal (Al), a reactive rare earth element (Sc), and a noble metal (Au) may produce tunable band structure or enhanced carrier transport. The material family is of interest in advanced materials research for high-performance semiconductors and possibly thermoelectric or photonic devices, though practical industrial adoption remains limited pending further characterization and scalable synthesis methods.
