Key Properties
Cross-validated computational properties for TeAsIr, 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.

How It Compares
Within the platinum-group alloy catalysts class.
Compared to other platinum-group alloys like As2Ir or P3Ru, TeAsIr occupies a specific niche by balancing its semiconducting nature with significant thermodynamic stability. While many siblings in this class focus on metallic conductivity, TeAsIr offers a different electronic profile that distinguishes it from more common metallic catalysts like BaPd or Ga2Ru.
