Abstract
Emulating a biological synapse is desired for overcoming von-Neumann bottleneck and memory wall issues in semiconductor memories. In this regards, neuromorphic memristors have gained great attention due to their excellent data storage capability and fast response, while reducing energy consumption is still challenging. Herein, we fabricated a resistive switching memory with a heterostructure, consisting of MXene (Ti3C2TX) nanosheets blended with polyvinylidene fluoride (PVDF). The device was fabricated by simple solution casting and spin-coating, followed by mild heat treatment. The device operated in low voltage range (-0.12 V to 0.42 V) with a high ON/OFF ratio and a rectification ratio of 108. We confirmed non-volatile memristive characteristics with a retention time exceeding 104 seconds and robust switching endurance over multiple cycles. Synaptic plasticity was demonstrated, and neuromorphic simulations based on measured device parameters achieved ~94% MNIST recognition accuracy.
