a Scanning electron microscopy image of the nanoscale PBFCL10 synapse crossbar array. b Current–voltage characteristics of the PBFCL10 device showing bistable switching behavior. c Device resistance in immediate response to an applied voltage stimulus. The amplitude of the driving voltage is 2.5 V. d Continuous modulation of device conductance in 32 quantized states with respective switching power consumption. e–g Retention performance with respective reading power consumption, C2C, and D2D statistics of the 32-state quantized conductances. h Comparison of the device linewidth, crossbar array size, and switching uniformity of the PBFCL10 neuromorphic matrix and other state-of-the-art organic devices as reported in refs. 12,30,31,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59.
