About IrRu
IrRu is a metallic binary alloy composed of iridium and ruthenium. As a member of the platinum-group alloy family, it exhibits characteristic metallic electronic properties, lacking a band gap and facilitating efficient electron transport. Its status as a near-hull stable phase suggests that it is a viable candidate for synthesis and experimental investigation in high-performance material applications. The compound is supported by a significant body of structural data, reflecting its prominence in computational materials science databases. It serves as a critical building block for researchers exploring the synergistic effects of combining heavy transition metals to tune catalytic activity. Its potential utility lies in its ability to withstand demanding environments, making it a focus for studies involving surface reactivity and electrochemical processes.
Key Properties
Cross-validated computational properties for IrRu, 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.
