S2N
S2N is a semiconducting binary compound of sulfur and nitrogen that is generally considered thermodynamically unstable.
About S2N
S2N is a binary nitrogen-sulfur compound that exhibits semiconducting electronic behavior. Despite its relatively high structural data availability across multiple databases, it is characterized as thermodynamically unstable, existing above the convex hull of stable phases. This suggests that while it can be modeled or synthesized under specific conditions, it does not represent a ground-state configuration. Its role remains primarily of interest in fundamental materials research rather than large-scale industrial deployment.
Key Properties
Cross-validated computational properties for S2N, 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.

How It Compares
As a unique nitrogen-sulfur binary phase, S2N occupies a distinct position in materials science where its metastability makes it a subject of significant theoretical curiosity. Unlike more common, stable binary chalcogenides, this compound serves as a case study for exploring the limits of structural stability in non-metal systems.
