Abstract

The space charge polarization/depolarization is considered, and to relate the geometrical arrangement of constitutive phases to the dielectric response, three space charge dielectric constants, viz., trapped space charge dielectric constant ε t, drift space charge dielectric constantε d and dielectric constant ε are modeled. It is observed that the order of ε t is same for AgI and 0.9[0.75AgI:0.25AgCl]:0.1SiO2 nanocomposite in β− and α−phases. In β− phase, ε d and ε are 10 times larger and 10 times smaller in the second system of respective β− and α−phases. In β− phase, the ionic concentration provides the main contribution to the dielectric response of both systems, and in α− phase, the ionic mobility has the main contribution to the dielectric nature.
