Mg2SnN2
Mg2SnN2 is a ternary magnesium tin nitride compound that exhibits semimetallic electronic properties and is currently identified as a metastable phase.
About Mg2SnN2
Mg2SnN2 is a ternary nitride compound composed of magnesium, tin, and nitrogen. Given its electronic character as a near-zero-gap material, it sits at the threshold between semiconducting and metallic behavior, making it an intriguing subject for fundamental electronic structure studies.
Because it exists above the thermodynamic hull, this compound is considered metastable or unstable under standard conditions. Its presence across multiple structural databases highlights its role as a theoretical candidate in the exploration of complex nitride phases.
Key Properties
Cross-validated computational properties for Mg2SnN2, 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.
