(a) Equivalent circuit: device structure composed of electrode resistor (mostly due to spreading resistance in bottom electrode) serially connected to a set of parallel cell resistance and cell capacitance . Apparent voltage is larger than the actual cell voltage . (b) Simulated on → off switching voltage versus pulse widths for various device sizes. (c) Simulated off → on switching voltage versus pulse widths for various device sizes.
