Conductivity and dielectric studies on (Na_(0.4)Ag_(0.6))_2PbP_2O_7 compound

摘要

Electrical properties of the (Na_(0.4)Ag_(0.6))_2PbP_2O_7 compound were studied using complex impedance spectroscopy in the frequency range 200 Hz-5 MHz and temperature range (484-593 K). Combined impedance and modulus plots were used to analyse the sample behaviour as a function of frequency at different temperatures. Temperature dependence of d.c. and a.c. conductivity indicates that electrical conduction in the material is a thermally activated process. The frequency dependence of the a.c. conduction activation energy was found to obey a mathematical formula.
