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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of SrTiN2. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
