TaVW2
TaVW2 is a semiconducting ternary transition metal compound that exists as a metastable phase.
About TaVW2
TaVW2 is a complex ternary compound composed of tantalum, vanadium, and tungsten. As a semiconducting material, it represents an interesting subject for researchers investigating the electronic properties of multi-element transition metal systems. Its existence is documented across multiple structural databases, reflecting ongoing interest in its potential configurations.
Because this compound resides above the thermodynamic hull, it is considered a metastable phase. This classification suggests that while it can be synthesized under specific conditions, it may require precise control over processing parameters to maintain its structural integrity compared to more stable, ground-state materials.
Key Properties
Cross-validated computational properties for TaVW2, 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.
