F9RbU2
F9RbU2 is a semimetallic rubidium uranium fluoride that is theoretically stable enough to be a target for laboratory synthesis.
About F9RbU2
F9RbU2 is a complex fluoride compound containing rubidium and uranium. Its electronic structure characterizes it as a near-zero-gap material, placing it in the semimetallic regime which is of significant interest for fundamental condensed matter studies.
As a near-hull phase, this compound is considered a promising candidate for experimental synthesis. The presence of multiple reported structures suggests a rich configurational landscape, making it a subject of interest for researchers investigating uranium-based inorganic chemistry.
Key Properties
Cross-validated computational properties for F9RbU2, 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.
