· Bi2Te0.1Se2.9

Bi2Te0.1Se2.9 is a tellurium-selenium compound belonging to the bismuth chalcogenide family, which are narrow-bandgap semiconductors with strong thermoelectric properties. This specific composition represents a selenium-rich variant within the well-studied Bi2Te3–Bi2Se3 solid solution system, commonly investigated for optimizing thermoelectric performance through controlled doping and compositional tuning. Engineers select materials in this family for applications requiring efficient thermal-to-electrical energy conversion or solid-state cooling, where the tunability of the Te/Se ratio allows trade-offs between electrical conductivity, thermal conductivity, and Seebeck coefficient to match specific operating conditions.

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.
