SrTiN2
SrTiN2 is a thermodynamically stable semiconducting nitride material used in advanced materials research.
About SrTiN2
SrTiN2 is a semiconducting ternary nitride that sits firmly on the convex hull, indicating significant thermodynamic stability. Its composition of strontium, titanium, and nitrogen allows for a unique electronic structure that researchers are investigating for potential use in next-generation electronic devices.
Because it is a stable member of the nitride family, this compound serves as a valuable subject for computational and experimental study. Its ability to maintain structural integrity makes it a promising candidate for materials science applications where reliable semiconducting behavior is required.
Key Properties
Cross-validated computational properties for SrTiN2, 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.
