Ferroelectric polymer thin-film memristors with asymmetric top electrodes

Abstract

A type of ferroelectric polymer thin-film memristors is demonstrated to show their potential in the emulation of synaptic plasticity. The memristive characteristics of the device arise from the design of asymmetric top electrodes capacitively coupled with a floating bottom electrode, which enables the local modulation of ferroelectric polarization in the ferroelectric terpolymer film. Basic synaptic functions, such as continuous increase/decrease in synaptic weight and paired-pulse facilitation, are successfully emulated using the ferroelectric polymer memristors. This work provides a promising approach to implementing ferroelectric mechanism in electronic synapses.

Voltage-Mode Ferroelectric Synapse for Neuromorphic Computing

“…34 In recent years, several studies have adopted P(VDF−TrFE−CTFE) as the active layer in artificial synaptic devices. 35 These studies demonstrated the potential of this material for neuromorphic computing. However, there are still some challenges that need to be addressed to make the use of P(VDF−TrFE−CTFE) in artificial synaptic devices more feasible.…”

“…Ferroelectric materials have spontaneous polarization that can be reversed by an external electric field. , This property makes them suitable for use in synaptic devices as it allows them to store and manipulate the synaptic weight in a similar manner to biological synapses. − Therefore, ferroelectric materials have been widely studied for their potential applications in the development of artificial synaptic devices. − One of the most promising ferroelectric materials is the organic ferroelectric material poly­(vinylidenefluoride–trifluoroethylene–chlorotrifluoroethylene) [P­(VDF–TrFE–CTFE)], which has been extensively investigated for its lower cost, lower processing temperature, and higher flexibility .
