RbIO2
RbIO2 is a metastable, semiconducting compound containing rubidium, iodine, and oxygen that exists in several distinct structural forms.
About RbIO2
RbIO2 is a complex inorganic compound composed of rubidium, iodine, and oxygen. As a semiconducting material, it exhibits electronic properties that distinguish it from simple ionic salts, positioning it as a subject of interest for fundamental solid-state research. The compound is characterized by its metastable nature, as it sits above the thermodynamic hull. Despite this, multiple structural variations have been identified across databases, highlighting the complex coordination chemistry possible within this chemical system.
Key Properties
Cross-validated computational properties for RbIO2, 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.
