CaVO3
CaVO3 is a semiconducting calcium vanadium oxide that is considered a viable target for experimental synthesis.
About CaVO3
CaVO3 is a complex oxide composed of calcium, vanadium, and oxygen. As a semiconducting material, it represents an interesting candidate for electronic and structural investigations in solid-state chemistry.
Its status as a near-hull compound suggests that it is likely synthesizable under appropriate laboratory conditions. With multiple reported structures across various databases, it serves as a subject of interest for researchers studying vanadium-based oxides and their potential physical properties.
Key Properties
Cross-validated computational properties for CaVO3, 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.

Reported Structures
Lowest-energy structures reported for CaVO3, ranked by energy above hull.
| Space GroupSymmetry classification of the crystal arrangement. The number is the international space-group index. | Crystal SystemBroad lattice family, such as cubic, tetragonal, monoclinic, or triclinic, derived from unit-cell symmetry. | Band Gap (eV)Electronic gap calculated for this specific reported structure, measured in electronvolts. | E above hull (eV/atom)Thermodynamic distance from the convex hull for this structure, normalized per atom. Lower is generally more stable. | E/atom (eV)Computed total energy normalized per atom. Use energy above hull, not this value alone, when comparing stability. | Density (g/cm³)Mass per relaxed crystal volume, reported in grams per cubic centimeter. |
