Large Resistive Switching in Ferroelectric BiFeO₃ Nano‐Island Based Switchable Diodes

Abstract

Comparison between piezoelectric force microscopy images and current-voltage data consecutively obtained using conductive atomic force microscopy below transition voltages for a highly oriented ferroelectric BiFeO3 nano-island confirms that ferroelectric polarization reversal induces transitions of forward-direction, and thus down- and up-polarization is accompanied by positive- and negative-forward diode-like behavior, respectively.
