VHO
VHO is a semiconducting vanadium-based compound that exists in a metastable state.
About VHO
VHO is a semiconducting compound composed of vanadium, hydrogen, and oxygen. As a material that sits above the thermodynamic hull, it is characterized by its inherent instability under standard conditions, representing a metastable phase of interest for fundamental research into vanadium-oxygen-hydrogen systems. Its existence is documented across multiple structural databases, highlighting its role as a subject of computational investigation. While it lacks the stability of more common binary oxides, its unique electronic nature makes it a notable entry for those studying complex phase spaces in transition metal chemistry.
Key Properties
Cross-validated computational properties for VHO, 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.
