Enhanced thermoelectric properties of Au nanodot-included Bi₂Te₃ nanotube composites

Abstract

Herein, we report on a scalable synthesis of Au nanodot (Au-ND)/Bi₂Te₃ nanotube (BT-NT) nanocomposites by the bottom-up synthesis of hybrid raw materials and subsequent spark plasma sintering, and their thermoelectric properties were systematically compared with those of Au-doped Bi₂Te₃ compounds.
