About Li3VF6
Li3VF6 is a complex fluoride material characterized by its semiconducting electronic nature. As a thermodynamically stable phase residing on the convex hull, it represents a robust configuration within the lithium-vanadium-fluorine system.
Its structural diversity is evidenced by numerous reported configurations across major materials databases. This stability and electronic profile make it a subject of interest for researchers investigating ion-conducting materials and solid-state chemistry.
Key Properties
Cross-validated computational properties for Li3VF6, 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.
