Al2 Au1

Al₂Au is an intermetallic compound combining aluminum and gold in a 2:1 stoichiometric ratio, classified as a semiconductor material. This is primarily a research compound studied for its electronic and structural properties rather than a widely commercialized engineering material. The Al-Au system is of interest in materials science for understanding intermetallic phase formation, potential thermoelectric applications, and as a model system for gold-containing binary alloys used in microelectronics and specialty applications.
