Thermoelectric Properties of SnO2/Bi2Te3 Composite

Year: 2021

Type: article

Abstract: In this study, SnO2 nanoparticles of wt% 2, 4, 6, and 8 were uniformly composite in Bi2Te3 matrix. SnO2 nanoparticle was synthesized using co-precipitation method. The result shows that based on XRD and EDS analysis the composites do not contain any impurities. The thermoelectric properties of the composites strongly depend on the Seebeck coefficient. The highest value of Seebeck coefficient of -177 µV/K is obtained at around 375 K for the 4% SnO2/Bi2Te3 sample. This yields the highest value of the power factor of 4.0 × 10-3 Wm-1K-1 compared to the pure Bi2Te3 synthesized using the same procedure by 14.3%. This result demonstrates that the thermoelectric properties of Bi2Te3 can be improved using oxide nanoparticles.
