Ca5MgN4
Ca5MgN4 is a semiconducting ternary nitride compound that is currently a subject of fundamental materials research.
About Ca5MgN4
Ca5MgN4 is a complex nitride material composed of calcium, magnesium, and nitrogen. It exhibits semiconducting electronic properties, positioning it within a class of materials often investigated for specialized optoelectronic or electronic applications.
While the compound has been identified across multiple structural databases, it is characterized as being thermodynamically situated above the hull. This suggests that the material may be metastable, requiring specific synthesis conditions to stabilize its crystalline framework.
Key Properties
Cross-validated computational properties for Ca5MgN4, 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.
