La3Ni
La3Ni is a metallic intermetallic compound formed from lanthanum and nickel that is considered potentially synthesizable due to its favorable thermodynamic stability.
About La3Ni
La3Ni is a metallic intermetallic compound composed of lanthanum and nickel. Its electronic structure is characterized by a lack of a band gap, identifying it as a conductive material suitable for specialized metallurgical studies.
Because it sits near the thermodynamic hull, La3Ni is considered a likely synthesizable phase. Its existence across multiple structural databases underscores its significance as a stable candidate for exploration in binary alloy systems.
Key Properties
Cross-validated computational properties for La3Ni, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of La3Ni. Tight agreement means computed properties can be trusted without re-running calculations.
