BaYF5 is a thermodynamically stable, insulating fluoride compound known for its structural complexity and potential utility in optical and dielectric applications.
About BaYF5
BaYF5 is a complex fluoride material characterized by its insulating electronic nature and high thermodynamic stability. As a member of the broader family of rare-earth barium fluorides, it sits securely on the convex hull, indicating a highly favorable structural configuration that resists decomposition under standard conditions. Its wide-band-gap nature makes it an intriguing candidate for applications requiring transparency across broad spectral ranges. The material is notable for its structural diversity, with numerous reported phases documented across major crystallographic databases, reflecting its versatility in solid-state chemistry. These characteristics position it as a robust platform for research into optical host materials and specialized dielectric components.
Key Properties
Cross-validated computational properties for BaYF5, 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.
