CErO4
CErO4 is a metastable, semiconducting ternary oxide containing cerium, erbium, and oxygen used in specialized materials science research.

About CErO4
CErO4 is a complex inorganic compound composed of cerium, erbium, and oxygen. As a semiconducting material, it exhibits electronic behavior that makes it a subject of interest for researchers investigating specialized functional oxides. Its metastable nature suggests that its synthesis and structural integrity are highly sensitive to processing conditions, requiring precise control to maintain its specific phase. The compound represents an intriguing intersection of rare-earth chemistry and oxide materials, offering potential pathways for developing advanced electronic or optical components. Because it exists in a metastable state, it is often studied to understand the limits of structural stability within complex ternary oxide systems.
Key Properties
Cross-validated computational properties for CErO4, 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.
