In2IrRh
In2IrRh is a semimetallic intermetallic alloy composed of indium, iridium, and rhodium, primarily studied for its electronic properties and potential catalytic applications.

About In2IrRh
In2IrRh is a complex intermetallic compound belonging to the class of platinum-group alloy catalysts. As a near-zero-gap semimetallic material, it exhibits unique electronic properties that bridge the behavior of metals and semiconductors, making it a subject of interest for fundamental studies in condensed matter physics and catalysis science. Despite its position above the thermodynamic hull, which suggests potential metastability, the compound is represented by multiple reported structures across research databases. Its synthesis and characterization contribute to the broader understanding of how noble metal combinations influence electronic structure and chemical reactivity.
Key Properties
Cross-validated computational properties for In2IrRh, 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.
