Key Properties
Cross-validated computational properties for Nb3N5, 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
Within the ultra-high-temperature ceramics class.
Within the broader category of ultra-high-temperature ceramics, Nb3N5 occupies a distinct niche compared to more conventional carbides like HfC or ZrC. While many of its siblings, such as TaN, are well-established refractory materials, Nb3N5 offers a unique semiconducting profile that differentiates it from the predominantly metallic or insulating behaviors found in other members of this class.
