CS3
Carbon trisulfide is an unstable, semiconducting binary compound consisting of carbon and sulfur atoms.

About CS3
Carbon trisulfide is an intriguing binary compound composed of carbon and sulfur. As a semiconducting material, it represents a specialized niche in carbon-sulfur chemistry, drawing interest from researchers exploring non-traditional bonding environments in chalcogenide systems.
Due to its position above the thermodynamic hull, this compound is considered metastable or unstable under ambient conditions. Its existence in numerous reported structures suggests a complex energy landscape that continues to be a subject of computational investigation.
Key Properties
Cross-validated computational properties for CS3, aggregated across 2 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.
