Key Properties
Cross-validated computational properties for Sb3Ir, 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.

How It Compares
Within the platinum-group alloy catalysts class.
Within the diverse family of platinum-group alloy catalysts, Sb3Ir occupies a distinct niche compared to siblings like As2Ir or GeRu. While many members of this class exhibit varying degrees of metallic or semiconducting behavior, Sb3Ir is notable for its near-zero-gap electronic character, which differentiates it from the more traditional metallic or insulating phases found in the broader group.
