· SmTe

SmTe is a rare-earth telluride semiconductor compound composed of samarium and tellurium, belonging to the family of binary chalcogenides. While primarily of research interest rather than widespread industrial production, SmTe and related rare-earth tellurides are investigated for thermoelectric applications, narrow-bandgap optoelectronics, and solid-state physics studies due to the unique electronic properties that rare-earth elements impart to tellurium matrices. Engineers and researchers consider such materials when seeking alternatives to conventional semiconductors in niche applications requiring specific band structures, thermal transport characteristics, or magnetic interactions unavailable in more common III-V or II-VI 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.
