About ErIn
ErIn is a metallic intermetallic compound composed of erbium and indium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these two elements, making it a subject of interest in fundamental materials science studies.
Its metallic nature suggests high electrical conductivity, which is characteristic of this class of binary intermetallics. With multiple reported structures across various databases, it serves as a valuable reference point for understanding rare-earth indium alloy systems.
Key Properties
Cross-validated computational properties for ErIn, 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.
