Ag3Au
Ag3Au is a thermodynamically stable intermetallic compound formed from silver and gold that exhibits metallic electronic properties.
About Ag3Au
Ag3Au is a metallic intermetallic compound composed of silver and gold. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these two noble metals.
This material is characterized by its metallic electronic behavior, lacking a band gap. With numerous reported structures across multiple databases, it is a well-documented example of how silver and gold interact to form distinct crystalline phases.
Key Properties
Cross-validated computational properties for Ag3Au, aggregated across 5 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
