Figure 2

The I–V curves measured for the upward (red) and downward (blue) BaTiO3 polarization states. The lower-right inset shows that the ROFF/RON resistance ratio is about 3,800 for a zero-bias regime and increases up to 6,000 for ±0.2 V. The upper-left inset shows the PFM images of the upward and downward polarization states after the I–V testing, illustrating that polarization is not affected by the I–V measurements.
