Caption: These dark-field transmission electron microscopy images show ferroelectric domain switching under various external biases. Without external current, the PZT film is split—the two opposing polarization are arranged in a head-to-head configuration. Crucially, with 󈝶 V applied in the bottom image, the domains near the PZT/Nb-STO interface fail to switch.
