ErGa6
ErGa6 is a thermodynamically stable, semimetallic intermetallic compound formed from erbium and gallium.
About ErGa6
ErGa6 is a stable intermetallic compound composed of erbium and gallium. Its electronic character is defined as near-zero-gap, placing it in the category of semimetallic materials that exhibit interesting transport properties due to the overlap of valence and conduction bands.
This material is notable for its structural complexity, as evidenced by its multiple reported crystallographic configurations across various databases. Its thermodynamic stability on the convex hull suggests it is a robust phase, making it a subject of interest for fundamental studies in rare-earth metal chemistry and electronic structure research.
Key Properties
Cross-validated computational properties for ErGa6, 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.
