About SrLaAl3O7
SrLaAl3O7 is a complex oxide composed of strontium, lanthanum, aluminum, and oxygen. As a thermodynamically stable phase residing on the convex hull, it represents a robust crystalline arrangement that maintains structural integrity under standard conditions.
This material functions as a wide-band-gap insulator, a characteristic that makes it highly relevant for applications requiring electrical isolation and optical transparency. Its stable nature allows it to serve as a reliable building block in the development of specialized ceramic and electronic components.
Key Properties
Cross-validated computational properties for SrLaAl3O7, aggregated across 1 database.
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
