BiSI
BiSI is a semiconducting bismuth sulfoiodide compound that is considered a promising candidate for experimental synthesis.
About BiSI
BiSI is a ternary bismuth sulfoiodide that functions as a semiconductor. Its electronic structure and composition suggest it is a material of interest for researchers investigating specialized optoelectronic properties within the bismuth-chalcogen-halide family.
As a near-hull stable compound, BiSI is considered a viable candidate for experimental synthesis. The existence of multiple reported structures across databases underscores its significance as a subject of ongoing structural and functional characterization in materials science.
Key Properties
Cross-validated computational properties for BiSI, 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.
