Description 685-688
In the present work, nanoparticles of pure Bi2Te3 and Ag doped Bi2Te3 have been prepared using hydrothermal
technique. The thermoelectric performance of bismuth telluride has been found to be improving with Ag doping. This may
be due to increase in the carrier concentration resulting in enhanced electrical conductivity of the material, and expected to
maintain its low thermal conductivity. The morphology, structural properties of the nanoparticles synthesized in this study
has been accessed through the utilization of scanning electron microscopy (SEM) and X-ray diffraction (XRD) technique.
Thin films ofas prepared powders ofpure Bi2Te3 and Ag doped Bi2Te3nanoparticles have deposited on to glass substrate
using thermal evaporation technique. The thermoelectric measurements of as synthesized materials have studied using an
indigenously developed setup. Seebeck coefficient for pure and Ag doped bismuth telluride thin films has found to be
150 μv°C-1and 182 μv°C-1, respectively.
