NaCrN
NaCrN is a semimetallic ternary nitride compound that is characterized by its metastable nature and structural complexity.
About NaCrN
NaCrN is a ternary nitride compound composed of sodium, chromium, and nitrogen. It exhibits a semimetallic electronic character, placing it in a unique position between traditional insulators and metallic conductors.
Due to its position above the thermodynamic hull, this material is considered metastable, representing a challenging synthetic target. It remains a subject of interest for researchers investigating the complex phase space of transition metal nitrides.
Key Properties
Cross-validated computational properties for NaCrN, 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
As a member of the ternary nitride family, NaCrN occupies a niche role where its semimetallic nature distinguishes it from more common wide-gap insulating nitrides. While it lacks direct structural siblings in this context, its status as an above-hull phase highlights the inherent difficulty in stabilizing specific transition metal-nitrogen bonding environments.
