Key Properties
Cross-validated computational properties for vanadium monoxide, 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.

How It Compares
Within the electrochromic and refractory-metal oxides class.
Within the broader class of electrochromic and refractory-metal oxides, VO represents a lower-oxidation state alternative to the more commonly utilized V2O5. While V2O5 is widely recognized for its prominent electrochromic switching capabilities, VO offers a distinct electronic environment that provides researchers with a different baseline for exploring phase transitions and optical modulation compared to its higher-valent siblings like MoO3 or WO3.
