Fig. 2: Electrical characteristics of the f-MDPE.

a Optical images of the f-MDPE on a polyimide (PI) substrate. b Cross-sectional transmission electron microscopy (TEM) image of the device. A single representative TEM image is measured. c I–V curves of the device with various compliance currents (ICC). The inset shows the nonlinearity and on/off ratio at 10 µA of ICC. d I–V curves of 160 cells in the array under 1 µA of ICC. e Repeated potentiation and depression cycles of the device. f Retention characteristics of 8 conductance states at 85 °C. g Long-term retention characteristics at various temperatures. h Endurance performance for LRS (red) and HRS (blue) up to 105 cycles at room temperature.
