Sr4RuN4
Sr4RuN4 is a metastable, semimetallic strontium ruthenium nitride used primarily in fundamental materials science research.
About Sr4RuN4
Sr4RuN4 is a complex quaternary nitride featuring strontium and ruthenium. Its electronic structure exhibits semimetallic behavior, characterized by a near-zero band gap that places it in a unique position between insulating nitrides and metallic conductors.
Due to its position above the thermodynamic stability hull, this compound is considered metastable. Its existence in multiple reported structures highlights its significance as a target for synthesis studies aimed at understanding the bonding interactions within transition metal-nitrogen frameworks.
Key Properties
Cross-validated computational properties for Sr4RuN4, 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.
