-based synaptic device with enhanced durability via self-curing performed from current annealing (CA) in synaptic fatigue occurring during repetitive learning. The conduction, degradation, and self-curing mechanisms of the 2D ferroelectric-based synaptic device are quantitatively elucidated by low-frequency noise (LFN) spectroscopy. The classification accuracy of the Canadian Institute for Advanced Research (CIFAR)-10 dataset with self-cured conductance is superior to that of the device with synaptic fatigue and recovers to the initial accuracy level. The simulation results of removing defect cells through self-curing in the 2D ferroelectric synaptic array can help reduce energy consumption in the long term. The experimental results emphasize adopting 2D ferroelectric materials for future neuromorphic computing.
