Study of structural and electrical properties of few double perovskite compounds

Abstract

A detail structure and electrical characterization of a few double perovskite and their perovskite counterpart have been performed. All the compounds are synthesized by wet chemical route known as sol-gel process. The samples are found to be in single phase and stoichiometric. The information about the molecular bonding is obtained from the FTIR spectra. The calculated band gap from UV-Visible spectra characterises the semiconducting and insulating nature of the material. The morphology of the materials has been studied through FESEM and finally the dielectric spectroscopy has been carried out for all compounds.
