About Al2MnSc
Al2MnSc is a metallic intermetallic compound characterized by its high thermodynamic stability, as evidenced by its position on the convex hull. This material is defined by its distinct atomic arrangement, which has been documented across multiple structural databases, reflecting significant interest in its crystalline configuration. Its metallic nature suggests potential utility in applications where conductive properties or structural robustness are required. As a stable phase, it serves as a reliable subject for researchers investigating the interplay between aluminum, manganese, and scandium in complex lattice systems.
Key Properties
Cross-validated computational properties for Al2MnSc, 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
