B2O6U2
B2O6U2 is a semiconducting uranium borate compound that is theoretically stable enough to be synthesized in a laboratory setting.
About B2O6U2
B2O6U2 is a complex uranium-based borate that exhibits semiconducting electronic behavior. Its structural framework, characterized by a specific arrangement of boron and oxygen polyhedra around uranium centers, suggests a unique potential for electronic or optical applications.
Because this compound is classified as near-hull stable, it is considered a prime target for experimental synthesis. The existence of multiple reported structural variations highlights its versatility and the interest it holds for researchers exploring actinide-based materials.
Key Properties
Cross-validated computational properties for B2O6U2, 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.
