semiconductor· Bi2Te0.4Se2.6
Bi₂Te₀.₄Se₂.₆ is a bismuth telluride-selenide solid solution, a narrow-bandgap semiconductor belonging to the V-VI compound family used primarily in thermoelectric applications. This material is engineered to optimize the Seebeck coefficient and thermal conductivity balance for intermediate-temperature thermoelectric devices, offering tunable performance between binary BiTe and BiSe end members. It is typically employed in research and specialized thermoelectric generators and coolers operating in the 300–500 K range, where its bandgap and carrier concentration can be optimized through composition 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.
