CeZr7O16
CeZr7O16 is a semiconducting ternary oxide of cerium and zirconium that is considered thermodynamically accessible for synthesis.
About CeZr7O16
CeZr7O16 is a complex oxide composed of cerium, zirconium, and oxygen. As a semiconducting material, it represents an interesting intersection of rare-earth and transition-metal oxide chemistry, characterized by a structural arrangement that sits near the thermodynamic hull, suggesting it is a viable candidate for experimental synthesis and characterization.
Its significance lies in its potential for specialized material science applications where the synergistic properties of cerium and zirconium are required. Given its presence in multiple structural databases, it serves as a subject of interest for researchers investigating stable, multi-component oxide systems for high-performance functional materials.
Key Properties
Cross-validated computational properties for CeZr7O16, 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.
