Ca2SnN2
Ca2SnN2 is a thermodynamically stable, semimetallic ternary nitride compound.
About Ca2SnN2
Ca2SnN2 is a thermodynamically stable ternary nitride that occupies a significant position on the convex hull. Its electronic character is defined as near-zero-gap, placing it in the semimetallic regime, which distinguishes it from typical insulating or semiconducting nitrides.
Because it is a well-reported structure, this compound serves as a key reference point for researchers studying the intersection of alkaline-earth metals and pnictogens. Its stability suggests potential for synthesis and integration into advanced electronic material studies.
Key Properties
Cross-validated computational properties for Ca2SnN2, 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.
