Electrical Parameters of Sno2 (1-X)zno(x) Nanocomposites Prepared by Solvothermal Method

Abstract

SnO 2(1-x) ZnO (x) (with x values 0.0,0.2,0.4,0.5,0.6,0.8,1.0) nanocomposite was prepared by a simple microwave assisted solvothermal method using ethylene glycol as solvent. The as-prepared samples are calcinated at 500 0 C. They were characterized using powder X-ray diffraction (PXRD) and the AC electrical parameter was studied with in the temperature range of 40-150 0 C. Both the dielectric loss factor and dielectric constant decreases with increase in frequency and increases with increase in temperature. It is due to the occurrence of space charge polarization. Increase in AC electrical conductivity with increase in frequency and temperature was noted and it is due to hopping of electrons. The results are reported here with.
