About rubidium oxide
Rubidium oxide is a binary inorganic compound composed of rubidium and oxygen. As a thermodynamically stable phase located on the convex hull, it represents a well-defined state within its chemical system, supported by extensive structural characterization across multiple databases.
Exhibiting semiconducting electronic characteristics, this material is of significant interest for fundamental studies in solid-state chemistry and alkali metal oxide physics. Its stable configuration makes it a primary subject for understanding the bonding and electronic behavior of heavy alkali metal oxides.
Key Properties
Cross-validated computational properties for rubidium oxide, 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.
