| 英文摘要 | Constructing a nanocomposite to introduce a coherent interface is an effective way to improve the property of thermoelectric material. Here, a series composites of Bi0.48Sb1.52Te3-x wt % Sb2Te3 (x = 0, 0.3, 0.5, 0.8, and 1.0) were synthesized, where the hydrothermally prepared Sb2Te3 nanosheets were intimately wrapped in the solid-state-reacted Bi0.48Sb1.52Te3 matrix. The formation of a coherent interface was observed and confirmed by the scanning electron microscopy characterization. As the Sb2Te3 content was over 0.5 wt %, the carrier mobility could increase by 26%, while the carrier concentration decreased by 9% compared to those of the pure matrix at 300 K, enhancing the power factor to 40.1 mu W/cm K-2. Moreover, the Bi0.48Sb1.52Te3-0.5 wt % Sb2Te3 sample exhibited a reduced lattice thermal conductivity of 0.83 W/m K at room temperature, resulting from the strengthened phonon scattering by interfaces. Combined with the manipulations of both the electronic and thermal transport by constructing a coherent interface, a maximum ZT of 1.05 was obtained in the x = 0.5 composite at 300 K, and it was improved by 20% compared with the result of the Bi0.48Sb1.52Te3 matrix. |
