Hysteresis in memristors produces conduction inductance and conduction capacitance effects

Abstract

Memristors are devices in which the conductance state can be alternately switched between a high and a low value by means of a voltage scan. In general, systems containing a...

Capacitive and Inductive Characteristics of Volatile Perovskite Resistive Switching Devices with Analog Memory

“… 51 , 52 This correlation of the impedance characteristics and transient behavior has been well-established by neuron-style models in halide perovskite solar cells and memory devices. 53 − 55 Moreover, this transient response of the voltage-dependent potentiation has been observed in voltage-gated potassium channels abundantly expressed in the human brain. 56 …”

“…This gradual increase in current response with the subsequent application of voltage pulses is the distinctive phenomenon of synaptic potentiation. ,, A closer look at the transient response of a single voltage pulse (Figure b) at applied voltages lower than the threshold voltage, a sharp initial transient peak is observed, subsequently followed by a gradual decay attributed to a capacitive charging of the device. , In contrast, at higher applied voltages, a gradual increase in current is observed after the gradual decay, indicating the slow inductive contribution once the capacitor has been charged, further reducing the total resistance . Finally, a sharp negative current peak is observed upon the removal of the voltage pulse due to the internal voltage and the series resistance of the device. , This correlation of the impedance characteristics and transient behavior has been well-established by neuron-style models in halide perovskite solar cells and memory devices. − Moreover, this transient response of the voltage-dependent potentiation has been observed in voltage-gated potassium channels abundantly expressed in the human brain …”
