CoIrLa2
CoIrLa2 is a semiconducting ternary alloy composed of cobalt, iridium, and lanthanum that is primarily studied for its structural and electronic properties.
About CoIrLa2
CoIrLa2 is a complex ternary alloy featuring cobalt, iridium, and lanthanum. As a member of the platinum-group alloy catalyst class, it exhibits semiconducting electronic behavior, making it an intriguing subject for research into specialized catalytic surfaces and electronic materials.
While this compound has been identified across multiple structural databases, its thermodynamic profile indicates it sits above the stability hull. This suggests that while it can be synthesized in specific structural configurations, it remains a metastable phase of significant interest for fundamental materials science studies.
Key Properties
Cross-validated computational properties for CoIrLa2, 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.
Compared to more common or stable platinum-group alloys like LaRh or IrSe2, CoIrLa2 occupies a more precarious thermodynamic position. While many of its class members are characterized by high stability, CoIrLa2 represents a more elusive phase that challenges our understanding of how transition metal and lanthanide combinations influence electronic properties in catalytic systems.
