AsEuGa
AsEuGa is a thermodynamically stable, semimetallic ternary compound containing arsenic, europium, and gallium.
About AsEuGa
AsEuGa is a unique ternary compound composed of arsenic, europium, and gallium. As a thermodynamically stable phase residing on the convex hull, it represents a robust configuration within its chemical system, offering researchers a reliable baseline for studying complex intermetallic interactions.
Characterized by a near-zero-gap electronic structure, this material functions as a semimetal. Its electronic nature makes it a subject of interest for fundamental studies into how rare-earth elements influence the conductive pathways of pnictide-based ternary systems.
Key Properties
Cross-validated computational properties for AsEuGa, 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.
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 AsEuGa. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
