Changes in the apparent coercive voltage for the Pt/PZT/Pt and capacitors. The inset figure shows the hysteresis loops for the respective capacitors under a voltage enough to saturate the polarization.
Changes in transient switching currents for (a) the Pt/PZT/Pt and (b) capacitors during polarization reversal from upward to downward direction. Inset figures correspond to reversal from downward to upward polarization.
(a) Changes in the as a function of the applied voltage for the Pt/PZT/Pt and capacitors with various layer thicknesses . The solid lines are a linear fit of the data to Eq. (1). (b) Dependence of the switching resistance on for the different direction of polarization reversal. (c) Changes in extracted from different methods, i.e., transient and hysteresis loop, as a function of .
Applied pulses for the pulse switching measurement and a schematic diagram showing the polarization and charge distribution for the reversal processes (a) from upward to downward polarization and (b) from downward to upward polarization.
