· Mo4 Se6 S2

Mo4Se6S2 is a layered transition metal chalcogenide semiconductor composed of molybdenum, selenium, and sulfur atoms. This mixed-chalcogenide compound belongs to the family of two-dimensional (2D) materials and is primarily of research and developmental interest for next-generation electronic and optoelectronic devices. The material is notable for its tunable bandgap and favorable properties for applications requiring ultrathin semiconducting layers, offering potential advantages over single-chalcogenide alternatives (such as MoS2) in terms of band structure engineering and device performance optimization.

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.
