About ErGaNi
ErGaNi is a metallic intermetallic compound composed of erbium, gallium, and nickel. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these three elements that maintains its integrity under standard conditions. Its metallic nature suggests high electrical conductivity, making it a subject of interest for fundamental studies in solid-state physics and materials science. Given its presence across multiple structural databases, it serves as a reliable reference point for researchers investigating ternary rare-earth transition metal systems. The compound is primarily utilized in academic and industrial research settings to explore the interplay between rare-earth magnetism and transition metal electronic behavior.
Key Properties
Cross-validated computational properties for ErGaNi, 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 ErGaNi. Tight agreement means computed properties can be trusted without re-running calculations.
