a Schematic of biological neuron with a core integrate-and-fire function. b Dynamic membrane potential generation process based on ion channel. c Volatile resistive switching curves under different compliance currents of 100 nA, 1 μA, and 10 μA. d Current-time curve of volatile device under s mall pulses (0.5 V, 1 ms) without response. The fire threshold is 1 pA. e Integrate-and-fire function realized by applying pulses of 1 V/ 1 ms. f Integrate-and-fire function with enhanced response under pulses of 1.5 V/ 1 ms. g Conductive atomic force microscopy surface map of Ag/MoS2/HfAlOx film under different scanning voltage values of 0, 5, and 10 V. Scale bar, 200 nm. h Schematics of integrate-and-fire behavior of memristive neuron under pulses. i Calculated artificial neuron power under continuous pulses of 1.5 V/1 ms. j Comparison of firing energy consumption in recently reported artificial neurons.
