RbSb2
RbSb2 is a stable, semiconducting binary compound formed from rubidium and antimony.
About RbSb2
RbSb2 is a binary intermetallic compound composed of rubidium and antimony. It exists as a thermodynamically stable phase, sitting directly on the convex hull, which indicates a robust structural configuration under standard conditions. As a semiconducting material, it offers unique electronic properties that distinguish it from simple metallic alloys. Its structural diversity is highlighted by multiple reported configurations across various databases, making it a subject of interest for fundamental materials research.
Key Properties
Cross-validated computational properties for RbSb2, 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.
