Complex impedance analysis and relationships with electrical conductivity, and dielectric constants
Fathy Salman · The Arab Journal of Scientific Research · 2018
AC impedance spectroscopy is a valuable tool for studying both the bulk transport properties of a material and the ac conductivity and the dielectric properties.The principle of the impedance analysis method is based on measurements of the sample impedance taken over a wide range of frequencies and then analysed in the complex impedance plane . The mathod was firstly applied to solid electrolytes problems by Bauerle(19)and then used by many workers for various superionic conductors. The impedance analysis method requires the determination from the measurements two parts of the complex impedance of the sample Z* = Z' + J Z''. The main parameters Rand C are deduced from the analysis of impedance method
