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.
