Its structural diversity is highlighted by multiple reported configurations across major databases. This versatility in atomic arrangement provides a foundation for investigating its behavior in various solid-state environments and potential technological roles.
Key Properties
Cross-validated computational properties for sodium orthoborate, 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.
