Temperature dependences of ferroelectricity and resistive switching behavior of epitaxial BiFe |
I – V resistive switching loops each measured as a function of bias voltage sweep-rate for three different temperatures: (a) 253 K; (b) 298 K; (c) 373 K. The inset in panel (c) shows the P – V loops tested at different testing durations. Here, NRS stands for new resistive switching. |
