W3O10
W3O10 is a semiconducting tungsten oxide that exists as a metastable phase within the group of refractory-metal oxides.
About W3O10
W3O10 is a semiconducting oxide composed of tungsten and oxygen. It belongs to the broader class of refractory-metal oxides, which are recognized for their structural complexity and potential utility in advanced electronic and optical devices.
Due to its position above the thermodynamic hull, this compound is considered metastable. Its existence across multiple reported structures highlights the intricate coordination chemistry inherent to tungsten-oxygen systems, making it a subject of interest for fundamental materials research.
Key Properties
Cross-validated computational properties for W3O10, 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.
