Abstract

Nano-structured Bi₂Te₃, Polyaniline (PANI) and PANI/ Bi₂Te₃ were synthesized by Solvothermal method. The crystallite size, Strain, inter-chain separation and unit cell volume were calculated from the X-ray diffraction (XRD) results by using Win fit and Unit cell software. The Gamma irradiation (γ-rays) with dose 50 KGy affects the peaks positions for the PANI samples whereas; it affects the intensity of Bi₂Te₃ samples. Thermal conductivity measurements were investigated from the differential scanning calorimeter (DSC) with respect to Indium (In) melting temperature curve. 50 KGy dose does not show a remarkable change in the PANI and PANI/ Bi₂Te₃ values on contrast the value of Bi₂Te₃sample was reduced.
