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.
