“…The Seebeck coefficient of Sb 2 Te 3 gradually decreases first, and then decrease with the sintering temperature increasing. The Seebeck coefficient is positive to the effective mass of the carriers and inversely positive to the 2/3 power of the carrier concentration [6]. The carrier concentration and the coupling effect of carrier effective mass under various sintering temperatures leads to the change of the Seebeck coefficient.…”

Sb2Te3-based materials are thermoelectric materials with the best performance in low-temperature regions. The preparation of antimony telluride by solid-state reaction method can shorten the production cycle and improve its electrical properties. The phase and electrical properties of the samples are characterized by XRD, SEM, Seebeck coefficient, and conductivity tester. The results show that when the holding time is 60 minutes and the sintering temperatures are 673 K, 723K, 773K, and 823 K, the resistivities of the synthesized samples are 1.68 mΩ·cm, 0.86 mΩ·cm, 0.67 mΩ·cm and 0.51mΩ·cm and the Seebeck coefficients of the synthesized samples are 99.580 μV/K, 93.633 μV/K, 96.018 μV/K and 70.152 μV/K, the maximum power factors of the samples is 1376.03 μWm−1·K−2 for sample synthesized at 773 K.
