“…11 This agrees with the stages of fatigue of polarization in ferroelectric bulk materials as well as thin films. [9][10][11] The stages of electric fatigue for antiferroelectric ceramics have not yet been fully understood, but it is assumed that these materials will undergo similar fatigue stages to the ferroelectric ones. According to the degradation of the maximum strain with the cycle number, the antiferroelectric fatigue in this study undergoes the stages from the incubation to the logarithmic period or, at most, to a saturation state under both cycling fields since there is no indication of recovery of the maximum strains even when at 10 8 cycles.…”

“…X-ray diffraction spectra of samples before and after fatigue display no apparent difference of characteristic peak, which seems to suggest that fatigue has no influence on crystallinity 14 or phase content 12 of P(VDF-TrFE) copolymer films. To explain polarization fatigue in inorganic ferroelectrics, Pawlaxzyk et al 15 proposed a hypothesis, which suggested that the inhibition of the seeds of opposite domain nucleation, caused by the nearbyelectrode injection of space charges, was the main mechanism of fatigue. On the basis of this hypothesis, we explained the frequency-, amplitude-, waveform-and profile-dependence of polarization fatigue in ferroelectric polymers.…”

In this study, we report the temperature dependence of polarization fatigue in ferroelectric copolymer films. Studies on temperature effect show a non-monotonic change of fatigue rate with increasing temperature. At temperature below 908C, fatigue endurance is weakened at higher temperature; while, at temperature above 908C, experimental data indicate that the higher the temperature, the lower the fatigue rate. X-ray diffraction spectra reveal little changes of characteristic peak before and after polarization fatigue. On the basis of the hypothesis of chargeinjection-induced fatigue, we propose a possible explanation of our experimental results.

“…Several ideas for charge injection have been presented in recent literature. [22][23][24] In the simplest, only charge directly injected into the film by application of an external electric field is considered. In this case, the amount of charge injected should simply be dependent on the amount of time that a capacitor has been under the externally applied field (as is the case when WO 3 is present in this work).…”

A conventional thin film capacitor heterostructure, consisting of sol–gel deposited lead zirconium titanate (PZT) layers with sputtered platinum top and bottom electrodes, was subjected to fatiguing pulses at a variety of frequencies. The fatigue characteristics were compared to those of a similarly processed capacitor in which a ∼20 nm tungsten trioxide layer had been deposited, using pulsed laser deposition, between the ferroelectric and upper electrode. The expectation was that, because of its ability to accommodate considerable oxygen non-stoichiometry, tungsten trioxide (WO3) might act as an efficient sink for any oxygen vacancies flushed to the electrode–ferroelectric boundary layer during repetitive switching, and hence would improve the fatigue characteristics of the thin film capacitor. However, it was found that, in general, the addition of tungsten trioxide actually increases the rate of fatigue. It appears that any potential benefit from the WO3, in terms of absorbing oxygen vacancies, is far outweighed by it causing dramatically increased charge injection in the system.
