Solvothermal synthesis of Sb2Te3 nanoplates under various synthetic conditions and their thermoelectric properties
Antimony telluride is a well-known p-type semiconductor material and considered to be one of the best candidates for thermoelectric applications. In this report, Sb2Te3 hexagonal nanoplates were synthesized by a simple solvothermal process under various synthetic conditions, and their morphology, size and uniformity changes were investigated. Synthesized nanoplates were sintered and the resulting bulk pellet showed low thermal conductivity. These results suggest that controllable synthesis of Sb2Te3 nanoplates and thermoelectric properties is feasible, and this methodology can be applied to other materials with a layered structure.
