About AgAu2Zn
AgAu2Zn is a ternary intermetallic compound composed of silver, gold, and zinc. It exhibits semiconducting electronic behavior, marking it as a distinct material within its structural group. The compound has been identified across multiple databases, reflecting ongoing research into its specific atomic arrangements.
Due to its position relative to the thermodynamic hull, this material is considered potentially unstable under standard conditions. Its existence in multiple reported structures suggests that synthesis pathways or specific environmental conditions may influence its stability and phase formation in experimental settings.
Key Properties
Cross-validated computational properties for AgAu2Zn, aggregated across 3 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.
