NaSb
NaSb is a thermodynamically stable semiconducting compound formed from sodium and antimony.
About NaSb
NaSb is a binary compound composed of sodium and antimony that exhibits semiconducting electronic behavior. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement within its chemical system.
The material is characterized by a significant degree of structural diversity, with numerous reported configurations across multiple databases. This structural richness makes it a subject of interest for researchers investigating the fundamental properties of alkali-antimonide systems.
Key Properties
Cross-validated computational properties for NaSb, 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 NaSb. Tight agreement means computed properties can be trusted without re-running calculations.
