TbN
TbN is a thermodynamically stable, semimetallic rare-earth nitride characterized by its diverse structural forms.
About TbN
Terbium nitride is a binary compound composed of terbium and nitrogen that exhibits a near-zero-gap electronic character. As a semimetallic material, it occupies a unique position in the landscape of rare-earth nitrides, offering distinct electronic properties that differ from traditional insulators or metals.
This compound is recognized for its thermodynamic stability, as it resides on the convex hull. Its structural versatility is highlighted by multiple reported configurations, making it a subject of interest for researchers investigating the fundamental behavior of lanthanide-based compounds in various physical environments.
Key Properties
Cross-validated computational properties for TbN, 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.
