Cu4La12O8S12
This complex quaternary compound is a member of the oxysulfide family, which are materials containing both oxygen and sulfur anions. These materials are primarily investigated in solid-state chemistry research for their unique structural properties and potential electronic behaviors.
Key Properties
Cross-validated computational properties for Cu4La12O8S12, 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.
