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

Antiferroelectric oxide thin-films: Fundamentals, properties, and applications

“…This gradually reduces the amount of reversible domains and subsequently diminishes the switchable polarization in AFE polycrystalline films [108]. Additionally, the local phase decomposition model has been proposed, suggesting a correlation with the local heat generated during the switching event in polycrystalline films [109].…”

Polarization fatigue in antiferroelectric (Pb,La)(Zr,Ti)O3 thin films: The role of the effective strength of driving waveform

“…2(e) and Ref. [14] and normalized dielectric constant dependence of the effective voltage, obtained from Fig. 1(e) and Fig.…”

“…1 and 2, we, again, adopted the concept of "effective electric strength" as we did previously [14]. According to Eq.…”

“…Recently, we found that the fatigue behavior of the AFE films is largely determined by the root-mean-square voltage of the external driving excitation rather than by the peak or average voltages [14]. Moreover, the effect of pulse width, driving voltage (or field) and frequency on fatigue behaviors of AFE thin films is also of concern and therefore motivates the present work.…”

“…Moreover, the effect of pulse width, driving voltage (or field) and frequency on fatigue behaviors of AFE thin films is also of concern and therefore motivates the present work. In our previous work [14], all driving waveforms used could be converted into their effective electric strength (i.e., root-mean-square voltage V rms ) according to…”
