CoW
CoW is a metallic binary intermetallic compound formed from cobalt and tungsten.
About CoW
CoW is a metallic intermetallic compound composed of cobalt and tungsten. As a metallic system, it exhibits characteristic electrical conductivity associated with its electronic structure, making it a subject of interest in fundamental materials science studies. Due to its position above the thermodynamic hull, CoW is considered a metastable phase. Its existence is supported by a significant volume of structural data, reflecting its complex behavior within binary transition metal systems.
Key Properties
Cross-validated computational properties for CoW, aggregated across 4 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of CoW. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
