| description | <p>Abstract</p> <p>A simple solvothermal approach has been developed to successfully synthesize n-type α-In<sub>2</sub>Te<sub>3 </sub>thermoelectric nanomaterials. The nanostring-cluster hierarchical structures were prepared using In(NO<sub>3</sub>)<sub>3 </sub>and Na<sub>2</sub>TeO<sub>3 </sub>as the reactants in a mixed solvent of ethylenediamine and ethylene glycol at 200°C for 24 h. A diffusion-limited reaction mechanism was proposed to explain the formation of the hierarchical structures. The Seebeck coefficient of the bulk pellet pressed by the obtained samples exhibits 43% enhancement over that of the corresponding thin film at room temperature. The electrical conductivity of the bulk pellet is one to four orders of magnitude higher than that of the corresponding thin film or p-type bulk sample. The synthetic route can be applied to obtain other low-dimensional semiconducting telluride nanostructures.</p> <p>PACS: 65.80.-g, 68.35.bg, 68.35.bt</p> |
