· In4 S6

In₄S₆ is an indium sulfide compound semiconductor belonging to the III-VI family of materials, characterized by a layered crystal structure and mixed-valence indium chemistry. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its tunable bandgap and potential for thin-film device fabrication make it attractive as an alternative to more established semiconductors like CdS or InP; however, it remains largely experimental with limited commercial deployment compared to conventional III-V or II-VI systems.

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.
