RbBiF3
RbBiF3 is a semiconducting halide perovskite material primarily investigated for its potential role in advanced photovoltaic and optoelectronic research.
About RbBiF3
RbBiF3 is a semiconducting material categorized within the halide perovskite class. Its electronic properties make it a subject of interest for researchers investigating potential semiconductor applications in optoelectronics and energy conversion technologies.
While this compound is structurally documented across multiple databases, it is characterized as being thermodynamically above the hull. This suggests that while it holds interest for fundamental materials science, it may present stability challenges compared to more robust perovskite structures.
Key Properties
Cross-validated computational properties for RbBiF3, 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.
