Surfactant‐Free Scalable Synthesis of Bi2Te3 and Bi2Se3 Nanoflakes and Enhanced Thermoelectric Properties of Their Nanocomposites (Adv. Mater. 10/2013)

Year: 2013

Type: article

Abstract: Nanomaterial-based thermoelectric devices request scalable production and compositional tolerance for reliable device performance. On page 1425 Unyong Jeong and co-workers suggest a large-quantity synthesis of surfactant-free nanoflakes of Bi2Te3 and Bi2Se3. 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% Bi2Se3 in the nanocomposites.
