YCoO3
YCoO3 is a stable, semiconducting oxide material utilized primarily in the study of oxygen-evolution catalysis for electrochemical applications.
About YCoO3
YCoO3 is a semiconducting oxide that sits firmly on the thermodynamic convex hull, indicating high structural stability. As a member of the oxide oxygen-evolution catalyst class, it serves as a critical subject for understanding charge transfer and surface reactivity in electrochemical systems.
The material is characterized by its robust structural framework, which has been extensively cataloged across multiple databases. Its electronic properties make it a compelling candidate for investigations into efficient water-splitting technologies and advanced catalytic processes.
Key Properties
Cross-validated computational properties for YCoO3, 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 YCoO3, 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. |
