CaGaN
CaGaN is a thermodynamically stable ternary nitride semiconductor composed of calcium, gallium, and nitrogen.
About CaGaN
CaGaN is a thermodynamically stable nitride semiconductor that sits firmly on the convex hull, indicating significant structural integrity. As a member of the nitride semiconductor class, it represents a specialized composition of calcium, gallium, and nitrogen that offers unique electronic characteristics for materials research.
This compound is of interest to researchers investigating the tunability of nitride-based systems. Its existence as a well-defined phase makes it a valuable subject for studying the interplay between alkaline earth metals and group thirteen nitrides in solid-state chemistry.
Key Properties
Cross-validated computational properties for CaGaN, 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 CaGaN. 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.

How It Compares
Within the nitride semiconductors class.
Unlike the widely utilized binary nitrides such as GaN or AlN, which are foundational to modern optoelectronics, CaGaN represents a more complex ternary phase. While GaN is a cornerstone of high-frequency power electronics and lighting, CaGaN serves as a distinct structural variant that expands the chemical space of the nitride family beyond simple binary systems.
