| description | Zinc antimonite, Zn4Sb3 is a promising thermoelectric material because of its high
thermoelectric performance and abundance of Zn and Sb in nature. Thus, in this study, samples
of Zn-Sb alloy were prepared using electrodeposition method because of its simple
experimental set-up, which also carried out in the room temperature. From the XRD results, all
samples deposited exhibit Zn-Sb alloy compositions. The best results were S1 and S3 as they
had dominant peaks that showed the crystal lattice of Zn4Sb3. From the SEM images, the
surface morphology of Zn-Sb alloy deposited samples showed were all-irregular, course and
rough structures. While, the atoms arrangement of the deposited samples were all flowery-like.
Based on physical properties characterization, the best samples; S1 (0.1M ZnCl2-0.1M SbCl3,
100mA, 120min) and S3 (0.1M ZnCl2-0.1M SbCl3, 50mA, 120min), were selected and
investigated their thermoelectric performances; electrical conductivity and Seebeck coefficient,
to determine their power factor, PF. Heat capacity of the samples was also examined to relate it
with thermal conductivity of Zn-Sb deposited samples. For thermoelectric performance, S1
obtained power factor of 1.37x10-7V/K. Ω.cm at 102°C with the Seebeck coefficient of
181μV/K. While as for S3, the power factor was 1.58x10-7V/K. Ω.cm with Seebeck coefficient
of 113μV/K at 101°C. From DSC analysis, it showed that S3 obtained higher Cp than S1. Cp for
S3 was 46.8093mJ/°C while S1 was 38.3722mJ/°C. |
