Carrier and morphologically tailored thermoelectric properties of MBi2O4 (M=Cu, Ni, and Zn) kusachiites

Enhanced Seebeck Coefficient of Cu-Bi-S Heterogeneous Composite Synthesized via Solvothermal Method

“…12 Aishwarya K. et al reported this material thermoelectric properties. The value of maximum electrical conductivity for this material is 0.245 Sm −1 at 663 K, the maximum Seebeck coefficient is 998 μVK −1 at 303 K, the maximum value at different temperature leads to obtain the maximum value of power factor 0.0106 × 10 −3 μWm −1 K −2 at 603 K. The minimum thermal conductivity of 1.234 Wm −1 K −1 obtained at 303 K. Finally, the material reported with zT of 0.0106 × 10 −4 at 603 K. 14 Here, we employing the substitutional method by replacing O anion from CuBi 2 O 4 with S anion to enhance the material power factor. The composite material was synthesized by using a simple and efficient solvothermal method.…”
