Synthesis and Thermoelectric Properties of Bi(2)Se(3) Nanostructures

Bismuth selenide (Bi(2)Se(3)) nanostructures were synthesized via solvothermal method. The crystallinity of the as-synthesized sample has been analyzed by X-ray diffraction, which shows the formation of rhombohedral Bi(2)Se(3). Electron microscopy examination indicates that the Bi(2)Se(3) nanopartic...

Sumario:Bismuth selenide (Bi(2)Se(3)) nanostructures were synthesized via solvothermal method. The crystallinity of the as-synthesized sample has been analyzed by X-ray diffraction, which shows the formation of rhombohedral Bi(2)Se(3). Electron microscopy examination indicates that the Bi(2)Se(3) nanoparticles have hexagonal flake-like shape. The effect of the synthesis temperature on the morphology of the Bi(2)Se(3) nanostructures has also been investigated. It is found that the particle size increases with the synthesis temperature. Thermoelectric properties of the Bi(2)Se(3) nanostructures were also measured, and the maximum value of dimensionless figure of merit (ZT) of 0.096 was obtained at 523 K.
