BaCeN2
BaCeN2 is a thermodynamically stable semiconducting ternary nitride containing barium and cerium.

About BaCeN2
BaCeN2 is a complex ternary nitride that exists in a thermodynamically stable state on the convex hull. As a semiconducting material, it represents a specialized niche in inorganic chemistry, characterized by the integration of barium and cerium within a nitrogen-based framework.
Its stability and electronic nature make it a subject of interest for researchers investigating new functional materials. With multiple reported structures, it serves as a foundational example for understanding the bonding and phase behavior of rare-earth-containing ternary nitrides.
Key Properties
Cross-validated computational properties for BaCeN2, 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.
