CaV4O8
CaV4O8 is a metastable semiconducting oxide containing calcium and vanadium that is primarily studied for its structural diversity.
About CaV4O8
CaV4O8 is a complex oxide composed of calcium, vanadium, and oxygen. As a semiconducting material, it exhibits electronic properties that distinguish it from simple metallic or insulating oxides, making it a subject of interest for fundamental solid-state chemistry studies.
Because it exists in a metastable state, this compound represents a unique structural configuration that requires specific synthesis conditions to achieve. Its existence across multiple reported structures suggests a rich potential for polymorphism and structural tuning in experimental settings.
Key Properties
Cross-validated computational properties for CaV4O8, 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.
