Weight update characteristics. Optical potentiation is obtained with 20 light pulses of tON = tOFF = 125 ms, λ = 405 nm, VG = 80 V, VTGr = 0.1 V. Electrical depression is obtained in dark, keeping VTGr at 0.1 V, and pulsing the gate voltage from 80 to 70 V, with a pulse width of 125 ms, using 20 voltage pulses. The cycle is repeated 3 times. Non-linearity factors for potentiation and depression are included in the plots.
