PrN2
PrN2 is a semimetallic praseodymium nitride compound that exhibits metastable thermodynamic characteristics.
About PrN2
PrN2 is a praseodymium-based nitrogen compound characterized by a near-zero-gap electronic structure, placing it in the category of semimetallic materials. Its composition reflects the complex bonding behaviors often found in rare-earth nitrides, where the interaction between lanthanide f-orbitals and nitrogen p-orbitals dictates its electronic behavior.
Despite its existence in multiple structural configurations, the compound is identified as being above the thermodynamic hull. This suggests that while it can be synthesized or modeled in various forms, it remains a metastable phase that requires specific conditions to maintain its structural integrity.
Key Properties
Cross-validated computational properties for PrN2, aggregated across 2 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.
