Popis:	Highlights The Li-mediated artificial synapses with a vertical two-terminal configuration capable of various synaptic behaviors, including bio-plausible synaptic plasticity, were successfully demonstrated for the first time and thoroughly explored Synaptic characteristics based on the progressive dearth of Li in Li x Co2 films are precisely controlled over the weight control spike, achieving extraordinary weight control functionality. In artificial neural network simulation, Li x CoO2-based neuromorphic system showed excellent accuracy comparable to the theoretical maximum due to the low nonlinearity and programming error, suggesting feasibility of hardware neural network implementation.
