Synaptic performance of the ReS2 synaptic devices. a The excitatory postsynaptic current (EPSC) triggered by the input pulse (− 1 V, 10 ms). b The inhibitory postsynaptic current (IPSC) triggered by a presynaptic spike (1 V, 10 ms). c Pair of output spikes of EPSC triggered by two consecutive input pulses (− 2 V, 10 ms, and with a 1-s interval between pulses). d Retention characteristics of the ReS2 synaptic devices after a − 3 V and 10 ms presynaptic spike
