Mn2N
Mn2N is a thermodynamically stable, metallic manganese nitride known for its structural diversity and potential in advanced materials research.
About Mn2N
Mn2N is a metallic manganese nitride that occupies a stable position on the thermodynamic convex hull. Its electronic character is defined by its metallic nature, lacking a band gap, which makes it a subject of significant interest for researchers studying transition metal nitrides. The material is characterized by a high degree of structural complexity, as evidenced by the numerous reported structures found across various databases. This diversity in atomic arrangement highlights its versatility and the potential for tuning its properties through synthesis methods. As a stable phase, it serves as a foundational material for investigating the interplay between nitrogen incorporation and the magnetic or electronic behavior of manganese-based systems.
Key Properties
Cross-validated computational properties for Mn2N, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
