Unipolar and bipolar fatigue in antiferroelectric lead zirconate thin films and evidences for switching-induced charge injection inducing fatigue

“…3,8,9 This model has been subsequently generalized to describe the fatigue problem in antiferroelectrics. 10 In particular, this model explains why polarization fatigue in antiferroelectric materials is much less severe than that in ferroelectrics under similar or even more severe bipolar electrical cycling as observed in the literature. [10][11][12][13] Moreover, this model indicates that antiferroelectric materials should show observable fatigue under unipolar electrical cycling, which has not been confirmed yet so far due to the lack of experimental data in the literature as mentioned above.…”

Effective driving voltage on polarization fatigue in (Pb,La)(Zr,Ti)O3 antiferroelectric thin films

“…Referring to the fatigue models and scenarios proposed in the literature, no one explicitly invokes the relationship between polarization fatigue and heat generation, except the LPD-SICI model [8,10,15,16,30]. So, let us now give a tentative interpretation of the phenomena observed in this work using the LPD-SICI theory.…”

“…In this model, the normalized P s (i.e., ðP s ðNÞ=P s ð0ÞÞ, in which P s ðNÞ and P s ð0Þ are P s after N cycles and initial P s , respectively) is given by [13,20,21] P s ðNÞ P s ð0Þ…”

“…Moreover, most of the models for fatigue in AFEs were originally proposed to describe the fatigue behaviors in FEs. The models proposed include domain pinning or locking by agglomerates of charged species [9,10], low stress due to 1801 phase switching instead of 901 phase switching [11], mechanical deterioration [12], and local phase decomposition arising from switching-induced charge injection (LPD-SICI) [13]. Therefore, the origin of fatigue in AFEs remains as a matter of high debate.…”

“…Therefore, it is crucial to understand the mechanism of fatigue in AFE materials and facilitate a better control over the design of devices. Unfortunately, there are only a few theoretical and experimental studies focusing on polarization fatigue in AFEs [9][10][11][12][13]. Moreover, most of the models for fatigue in AFEs were originally proposed to describe the fatigue behaviors in FEs.…”
