Ce3ZrO8
Ce3ZrO8 is a metastable semiconducting oxide containing cerium and zirconium.

About Ce3ZrO8
Ce3ZrO8 is a complex oxide composed of cerium, zirconium, and oxygen. As a semiconducting material, it exhibits electronic properties that distinguish it from simple binary oxides, making it a subject of interest for specialized functional applications.
Although it is classified as a metastable phase, the existence of multiple reported structures suggests a rich landscape for structural investigation. Its unique stoichiometry allows for complex atomic arrangements that are critical for understanding phase stability in multi-component cerium-zirconium systems.
Key Properties
Cross-validated computational properties for Ce3ZrO8, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of Ce3ZrO8. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
