Bismuthinite · Bismuth sulfide
Bismuthinite is a stable, semiconducting bismuth sulfide mineral widely studied for its potential in electronic and light-sensing applications.
About Bismuthinite
Bismuthinite is a naturally occurring, thermodynamically stable sulfide that crystallizes in a distinct orthorhombic structure. As a well-characterized semiconducting material, it has garnered significant attention for its potential in thin-film devices and energy conversion technologies.
Its electronic character makes it a subject of ongoing research for light-harvesting applications. Because it resides on the convex hull, it exhibits robust structural stability, which is essential for consistent performance in various electronic and sensing environments.
Key Properties
Cross-validated computational properties for Bismuthinite, aggregated across 4 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of Bi2S3. Tight agreement means computed properties can be trusted without re-running calculations.
