CaRuN2
CaRuN2 is a semimetallic ternary nitride compound characterized by its metastable nature and complex structural landscape.
About CaRuN2
CaRuN2 is a complex ternary nitride composed of calcium, ruthenium, and nitrogen. Its electronic structure is characterized as near-zero-gap, placing it in the regime of semimetallic materials which often exhibit unique transport properties useful in specialized electronic research.
Due to its position above the thermodynamic hull, this compound is considered metastable, representing a challenging synthetic target. The existence of multiple reported structures across various databases highlights its significance as a subject of ongoing investigation in solid-state chemistry.
Key Properties
Cross-validated computational properties for CaRuN2, 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.
