“…The origin of relaxation currents has been a point of disagreement. The most frequently considered physical interpretations of these currents are dipolar relaxation, 14,15 tunneling to empty traps close to electrodes, 16,17 charge injection, 18 electrode polarization, 19 and carrier hopping between localized states. 20 In spite of this diversity in transient mechanisms, the time-domain response of a dielectric follows in most of the cases the empirical Curie-Von Schweidler ͑C-VS͒ law: 16,21 …”
