Summary: | <p>Abstract</p> <p>Bismuth selenide (Bi<sub>2</sub>Se<sub>3</sub>) 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<sub>2</sub>Se<sub>3</sub>. Electron microscopy examination indicates that the Bi<sub>2</sub>Se<sub>3</sub> nanoparticles have hexagonal flake-like shape. The effect of the synthesis temperature on the morphology of the Bi<sub>2</sub>Se<sub>3</sub> nanostructures has also been investigated. It is found that the particle size increases with the synthesis temperature. Thermoelectric properties of the Bi<sub>2</sub>Se<sub>3</sub> nanostructures were also measured, and the maximum value of dimensionless figure of merit (ZT) of 0.096 was obtained at 523 K.</p> |
