BiBO2
BiBO2 is a stable, wide-band-gap insulating oxide composed of bismuth, boron, and oxygen.
About BiBO2
BiBO2 is a bismuth-based borate oxide that exhibits a wide-band-gap insulating electronic character. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement within the bismuth-boron-oxygen chemical space. Its structural integrity makes it a significant subject for researchers investigating stable inorganic oxides. The material has been characterized through multiple distinct structural configurations, reflecting a rich landscape of atomic arrangements. This diversity in its structural profile suggests potential utility in applications requiring stable, insulating dielectric materials or specialized optical components where wide-gap behavior is advantageous.
Key Properties
Cross-validated computational properties for BiBO2, 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.
