Surfactant-Free Scalable Synthesis of Bi sub(2)Te sub(3) and Bi sub(2)Se sub(3) Nanoflakes and Enhanced Thermoelectric Properties of Their Nanocomposites (Adv. Mater. 10/2013)

Surfactant-Free Scalable Synthesis of Bi sub(2)Te sub(3) and Bi sub(2)Se sub(3) Nanoflakes and Enhanced Thermoelectric Properties of Their Nanocomposites (Adv. Mater. 10/2013)

Nanomaterial-based thermoelectric devices request scalable production and compositional tolerance for reliable device performance. Unyong Jeong and co-workers suggest a large-quantity synthesis of surfactant-free nanoflakes of Bi sub(2)Te sub(3) and Bi sub(2)Se sub(3). The chemical composition of th...

Zusammenfassung:Nanomaterial-based thermoelectric devices request scalable production and compositional tolerance for reliable device performance. Unyong Jeong and co-workers suggest a large-quantity synthesis of surfactant-free nanoflakes of Bi sub(2)Te sub(3) and Bi sub(2)Se sub(3). The chemical composition of the heterostructured nanocomposites is precisely controlled by mixing the nanoflake suspensions. A maximum ZT (0.7 at 400 K) is achieved with a broad content of 10-15% Bi sub(2)Se sub(3) in the nanocomposites.
