AlInN2
AlInN2 is a semiconducting ternary nitride material that is considered a promising candidate for synthesis and integration into advanced semiconductor devices.
About AlInN2
AlInN2 is a ternary nitride semiconductor that sits near the thermodynamic stability hull, suggesting it is a viable candidate for experimental synthesis. As a member of the broader nitride family, it bridges the electronic properties of its constituent binary components, providing a tunable platform for semiconductor device design.
Its semiconducting nature makes it a subject of interest for researchers looking to expand the library of nitride-based materials. With multiple structural configurations reported in databases, it represents a versatile building block for advanced thin-film technologies and specialized electronic components.
Key Properties
Cross-validated computational properties for AlInN2, 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.
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 AlInN2. 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.
