RbErO2
RbErO2 is a stable, wide-band-gap insulating oxide containing rubidium and erbium.
About RbErO2
RbErO2 is a crystalline oxide compound composed of rubidium, erbium, and oxygen. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration within its chemical system, characterized by its insulating electronic nature and wide-band-gap behavior.
This material is of interest to researchers investigating the interplay between rare-earth elements and alkali metals in complex oxides. Its stable structure makes it a candidate for fundamental studies into electronic and optical properties relevant to specialized solid-state applications.
Key Properties
Cross-validated computational properties for RbErO2, 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.
