WF4
WF4 is a stable, semiconducting inorganic compound consisting of tungsten and fluorine atoms.
About WF4
WF4 is a binary inorganic compound composed of tungsten and fluorine. As a thermodynamically stable material located on the convex hull, it represents a robust phase within the tungsten-fluorine system. Its electronic character is defined as semiconducting, making it an interesting subject for studies into the fundamental behavior of transition metal halides. The compound is notable for its significant structural diversity, with numerous reported configurations across major materials databases. This wealth of structural data underscores its importance in understanding phase stability and bonding in high-oxidation state metal fluorides.
Key Properties
Cross-validated computational properties for WF4, 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.
