CaI3Rb
CaI3Rb is a thermodynamically stable, wide-band-gap insulating compound composed of calcium, iodine, and rubidium.
About CaI3Rb
CaI3Rb is a complex inorganic compound characterized by its insulating electronic nature and wide-band-gap profile. As a material that sits firmly on the convex hull, it exhibits significant thermodynamic stability, making it a robust candidate for structural and electronic studies.
Its unique composition of calcium, iodine, and rubidium allows it to function within specialized material frameworks. The existence of multiple reported structures across various databases underscores its importance as a subject of ongoing research in solid-state chemistry.
Key Properties
Cross-validated computational properties for CaI3Rb, 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.
