Al2Cd2Ce6S14
This complex quaternary sulfide belongs to a class of rare-earth chalcogenides often investigated for their unique structural properties and potential electronic behavior. Materials of this type are primarily studied in solid-state chemistry research to understand how the arrangement of rare-earth and transition metal ions influences crystal symmetry and physical characteristics.
Key Properties
Cross-validated computational properties for Al2Cd2Ce6S14, 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.
