The compound is recognized for its structural diversity, with multiple reported configurations across various databases. This structural flexibility highlights its potential utility in specialized ceramic applications where specific lattice geometries are required for performance optimization.
Key Properties
Cross-validated computational properties for La3ScO6, 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.
