IrN2
IrN2 is a semiconducting iridium nitride compound that exists as a metastable phase in materials research.
About IrN2
IrN2 is a semiconducting compound composed of iridium and nitrogen. Its electronic properties make it a subject of interest for researchers investigating the behavior of transition metal nitrides under various conditions. Given its position relative to the thermodynamic hull, it is considered a metastable phase. The high number of reported structures suggests significant interest in its potential configurations and synthesis pathways in materials science.
Key Properties
Cross-validated computational properties for IrN2, 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.
