IMPEDANCE SPECTROSCOPY: SEPARATION AND ASYMPTOTIC MODEL INTERPRETATION

Sioma Baltianski

Abstract

A new and efficient technique of impedance spectra interpretation is presented. The decomposition of the full impedance into separate parts is accomplished by fitting data using a parametric distribution function of relaxation times in a convoluted form. Each particular impedance element is presented as the asymptotic model in the next step. The result of this procedure is unambiguous. This is demonstrated using electroceramic samples in the ranges <i>T</i> = 200 - 475 °C and <i>f</i> = 10 mHz - 30 MHz.
