BErO2
BErO2 is a stable, wide-band-gap insulating oxide containing boron, erbium, and oxygen.
About BErO2
BErO2 is a complex oxide composed of boron, erbium, and oxygen. As a thermodynamically stable compound residing on the convex hull, it represents a robust structural configuration that is well-defined within current materials databases.
This material functions as a wide-band-gap insulator, a characteristic that makes it a subject of interest for specialized electronic and optical applications. Its structural integrity and electronic properties suggest it may serve as a foundational component in high-performance dielectric or ceramic systems.
Key Properties
Cross-validated computational properties for BErO2, 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.
