摘要：

The thermoelectric materials based on p-type Bi2Se3xTe3 ((1-x)) bulk products and dispersed with x compositions of Se (x=0.0, 0.2, 0.4, 0.6, 0.8, 1.0) were fabricated using standard solid-state microwave synthesis procedures. The products were characterized by X-ray diffraction (XRD). The XRD characterizations revealed that these products are pure Bi2Te3 and Bi2Se3 with uniform structures. The electrical properties of the Bi2Te3, Bi2Se3 and Bi2Se3xTe3 ((1-x)) samples were measured in the temperature range of 303-523 K. The highest value of the Seebeck coefficient was 176.3 mu V/K for the Bi2Se0.6Te2.4 sample, but only 149.5 and 87.4 mu V/K for the Bi2Te3 and Bi2Se3 samples, respectively.
