Ba3N2
barium nitride
Barium nitride is a semimetallic binary compound formed from barium and nitrogen that exhibits significant structural complexity.
About barium nitride
Barium nitride is a binary compound composed of barium and nitrogen. It exhibits a semimetallic electronic character, placing it in a unique position between traditional insulators and conductors within the alkaline earth metal nitride family.
Due to its position above the thermodynamic hull, this material is considered metastable under standard conditions. Its complex structural landscape, represented by numerous reported configurations across various databases, makes it a subject of interest for fundamental solid-state chemistry studies.
Key Properties
Cross-validated computational properties for barium nitride, aggregated across 4 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.
