Model for Charge Transport in Ferroelectric Nanocomposite Film

Figure 10

(a) Average anode and cathode fields for 10 vol% BaTiO₃ nanofiller and 30 vol% PVDF nanocrystallites are reduced due to the antiparallel polarization. The fields take up to 1 transit time to reach steady-state, with the anode field lowered by the proximity of the injected positive charge and (b) injected current density at the anode stabilizes after the 1 transit time.
