About Sr3SbN
Sr3SbN is a complex ternary compound composed of strontium, antimony, and nitrogen. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement within its chemical system. Its electronic character as a semiconductor makes it an intriguing candidate for specialized electronic and optoelectronic investigations.
The material is characterized by significant structural diversity, with multiple reported configurations across various databases. This structural richness suggests that Sr3SbN can adopt different symmetries, providing researchers with a versatile platform to study how atomic positioning influences the fundamental electronic properties of nitrogen-containing intermetallics.
Key Properties
Cross-validated computational properties for Sr3SbN, 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.
