Figure 2: PFM study of BFO nano-islands.

From: Selector-free resistive switching memory cell based on BiFeO3 nano-island showing high resistance ratio and nonlinearity factor

Figure 2

(a) AFM topography, (b) PFM amplitude, and (c) PFM phase images of BFO nano-islands. (d) Dependence of the PFM phase (red) and PFM amplitude (blue) on the applied voltage as swept between −5 V and +5 V, which are measured at a point on a single BFO nano-island. Polarization switching does not occur even with a high applied voltage.
