About rubidium iodide
Rubidium iodide is a thermodynamically stable inorganic salt that functions as a wide-gap insulator. Its electronic structure is characterized by a significant energy separation between the valence and conduction bands, making it a classic example of a robust ionic solid.
Due to its structural reliability and chemical stability, this compound is frequently utilized in specialized optical and radiation detection applications. It serves as a foundational material for researchers investigating the fundamental properties of alkali halides.
Key Properties
Cross-validated computational properties for rubidium iodide, 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.
