About rubidium fluoride
Rubidium fluoride is a simple inorganic salt composed of rubidium and fluorine. As a wide-gap insulator, it exhibits high electronic stability and exists as a thermodynamically stable phase on the convex hull, making it a reliable subject for fundamental materials research. The compound is characterized by its high structural consistency, supported by extensive data across multiple material databases. Its chemical behavior is typical of alkali halides, where the ionic bonding dictates its crystal structure and physical properties. It serves as a foundational material in solid-state chemistry for studying ionic lattice dynamics and halide interactions.
Key Properties
Cross-validated computational properties for rubidium fluoride, 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.
