Investigation on the Electrical Conductivity of PZT Modified by Manganese and Cerium

Abstract

PZT is a ferroelectric ceramic material that has acquired immense importance in the field of electronics industry. The main focus of this report is to present the electrical conductivity response of manganese and cerium modified lead zirconate titanate (PZT). The conductivity response has been investigated with respect to the frequency of applied AC electric field and temperature. The samples have been prepared by mixing high purity chemicals through a high-temperature solid-state route. The frequency response of electrical conductivity has been analyzed on the basis of Maxwell-Wagner and Koop’s model. The temperature response of electrical conductivity indicated that the compounds exhibit Arrhenius behavior.
