· Bi2S3

Bismuth sulfide (Bi₂S₃) is a narrow-bandgap semiconductor compound belonging to the V-VI family of materials, characterized by layered crystal structure and significant spin-orbit coupling effects. It appears primarily in research and emerging applications for thermoelectric energy conversion, infrared optics, and photocatalysis, where its tunable bandgap and high absorption coefficient offer advantages over conventional semiconductors; recent interest has focused on its potential in topological materials and quantum devices, though industrial deployment remains limited compared to established semiconductors like Si or III-V compounds.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
