· Sm8 Si4 Te4 O16

Sm₈Si₄Te₄O₁₆ is a rare-earth semiconductor compound combining samarium (a lanthanide element) with silicon, tellurium, and oxygen in a mixed oxide-chalcogenide structure. This is a research-phase material exploring rare-earth chalcogenide semiconductors, which are of interest for narrow-bandgap and mid-infrared applications where traditional semiconductors fall short. The samarium-silicon-tellurium family represents an emerging materials platform for optoelectronic and thermal management applications where the combination of rare-earth and chalcogenide components can offer tunable electronic properties and potential for high-temperature stability.

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.
