About Cerium
Cerium is a metallic chemical element that serves as a foundational material in materials science. It is recognized for its exceptional structural diversity, with numerous reported phases that highlight its complex behavior under varying conditions.
As a thermodynamically stable element, Cerium maintains a robust presence on the convex hull. Its metallic nature and unique electronic configuration make it a subject of extensive research for understanding phase transitions and alloying behavior in rare-earth systems.
Key Properties
Cross-validated computational properties for Cerium, aggregated across 4 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 Ce. 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.
