BaY2O4
BaY2O4 is a stable, insulating ternary oxide composed of barium, yttrium, and oxygen.
About BaY2O4
BaY2O4 is a complex oxide composed of barium, yttrium, and oxygen. As a thermodynamically stable phase located 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 an interesting candidate for electronic and optical applications where insulating behavior is required. Its composition suggests potential utility in specialized ceramic or dielectric research.
Key Properties
Cross-validated computational properties for BaY2O4, aggregated across 2 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.
