About Au1Na1Zn2
Au1Na1Zn2 is a complex ternary intermetallic compound composed of gold, sodium, and zinc. Its electronic character is defined as semiconducting, marking it as a distinct material within the broader landscape of metallic alloys and intermetallic phases.
Due to its position relative to the thermodynamic hull, this compound is considered metastable. While it has been identified across multiple structural configurations in computational databases, its synthesis and long-term stability remain subjects of significant interest for materials scientists studying complex phase spaces.
Key Properties
Cross-validated computational properties for Au1Na1Zn2, aggregated across 2 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.
