AlNi2Zn
AlNi2Zn is a metastable, semimetallic ternary intermetallic compound composed of aluminum, nickel, and zinc.
About AlNi2Zn
AlNi2Zn is a ternary intermetallic compound composed of aluminum, nickel, and zinc. Exhibiting a semimetallic electronic character, this material sits near the boundary of metallic and semiconducting behavior, making it a subject of interest for fundamental studies in condensed matter physics.
Due to its position above the thermodynamic hull, AlNi2Zn is considered a metastable phase. Its existence across multiple reported structures suggests that synthesis conditions play a critical role in stabilizing this specific arrangement of atoms, distinguishing it from more robust, ground-state intermetallics.
Key Properties
Cross-validated computational properties for AlNi2Zn, 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.
