Multiferroic properties of BiFeO3–Pb(Zr0.52Ti0.48)O3 solid solution

Relative Investigation on Microwave-Assisted Zr-Modified PbTiO3 and BaTiO3 Ferroelectric Ceramics for Energy Storage Application

“…The intrinsic characteristics of ceramics, such as their band gap energies are accountable for the increase in leakage current. Two alternative models, namely, the ohmic conduction model and the space charge limited current model, have been proposed previously to explicate the conduction mechanism in these systems . It is established that there is a direct relation between current density and power law, i.e., J ∝ E n .…”

“…Two alternative models, namely, the ohmic conduction model and the space charge limited current model, have been proposed previously to explicate the conduction mechanism in these systems. 51 It is established that there is a direct relation between current density and power law, i.e., J ∝ E n . For n = 1, the conduction is due to the ohmic conduction mechanism, and for n = 2, the conduction mechanism shifts to space charge limited current.…”
