VOF2
VOF2 is a stable, semiconducting vanadium oxyfluoride used in materials research.
About VOF2
VOF2 is a distinct vanadium oxyfluoride characterized by its semiconducting electronic nature. As a thermodynamically stable compound residing on the convex hull, it represents a robust phase that maintains structural integrity under standard conditions.
This material is of significant interest to researchers investigating the intersection of transition metal oxides and fluorides. Its stability and electronic properties make it a subject of ongoing study for applications requiring reliable semiconducting performance in complex chemical environments.
Key Properties
Cross-validated computational properties for VOF2, 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.
