BiI6K2Rb
BiI6K2Rb is a semiconducting bismuth-based halide material investigated for its potential utility in photovoltaic and optoelectronic technologies.
About BiI6K2Rb
BiI6K2Rb is a complex halide material categorized within the broader family of halide perovskite photovoltaics. As a semiconducting compound, it represents an interesting subject for researchers investigating alternative compositions for optoelectronic applications. Its structural arrangement is defined by the integration of bismuth and alkali metals within a halide framework.
While this compound is of interest for its electronic properties, it is currently characterized as being thermodynamically unstable relative to its constituent phases. This positioning above the hull suggests that while it may be synthesized under specific conditions, it remains a challenging candidate for long-term stability in practical device architectures.
Key Properties
Cross-validated computational properties for BiI6K2Rb, 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.

How It Compares
Within the halide perovskite photovoltaics class.
Unlike highly stable and widely studied perovskite benchmarks such as CsPbBr3 or CsSnI3, BiI6K2Rb occupies a more precarious thermodynamic position. While siblings like RbPbF3 or Cs4I12Sn4 are often explored for their phase behavior and structural versatility, BiI6K2Rb is distinguished by its bismuth-based chemistry, which serves as a focal point for researchers seeking to move beyond lead-based halide perovskite systems.
