(a) Schematic diagram of the pulse switching circuit employed in this study. Voltage of oscilloscope versus time plots when voltage pulse of duration (b) 5μs, (c) 0.5μs and (d) 0.25μs with various height were applied to 500 ^oC annealed STO film. Inset figures of (c,d) are the enlarged plots of discharging peaks.
