Rb3BiF6
Rb3BiF6 is a stable, wide-gap insulating halide perovskite used primarily as a structural model in materials science research.
About Rb3BiF6
Rb3BiF6 is a complex halide material characterized by its insulating electronic nature. As a member of the broader halide perovskite family, it represents a stable structural arrangement that has been identified across multiple computational databases, suggesting it is a viable candidate for experimental synthesis.
Its wide-gap electronic profile distinguishes it from narrow-gap semiconductors typically used in active photovoltaic layers. Instead, this compound serves as a critical structural model for understanding the stability and lattice dynamics of bismuth-based halide frameworks in high-performance material design.
Key Properties
Cross-validated computational properties for Rb3BiF6, 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.

How It Compares
Within the halide perovskite photovoltaics class.
Unlike the highly conductive and widely utilized CsPbBr3 or CsSnI3, which are optimized for light absorption in solar cells, Rb3BiF6 functions as a wide-gap insulator. While it shares the structural lineage of halide perovskites with materials like RbPbF3, its unique bismuth-based composition offers a different chemical pathway for exploring stable, non-toxic alternatives to traditional heavy-metal perovskites.
