Abstract

The glassy network system under investigation is prepared by using melt quench technique. The ac conductivity and dielectric behavior studied in ac frequency range (500Hz–1MHz) below glass transformation region. The correlated barrier hopping (CBH) model is used for interpreting the relation between the frequency exponent and temperature. The equation based on the Guintini model gives the value of maximum barrier height from the dielectric measurements. The compositional variation of conduction mechanism and dielectric parameters is studied to explore material’s nature.
