OECT (a) output characteristics, (b) transfer characteristics, and (c) transconductance as a function of device parameters for (from top to bottom) PE2-OE4, PE2-OE6, PE2-OE2OE2, PE2 OE2OE3, and PE2-OE3OE3 in 0.1 M NaCl/H2O electrolyte. The circled data points in (c) correspond to OECTs tested 5 months after fabrication, highlighting the robustness of the devices when stored in inert atmosphere. All values of W, d, L, VGS and VTh for each individual device are reported in Table S2.

(e-f) Corresponding evolution of the doping/dedoping kinetics (wavelength sampling at 620 nm) highlighting how the OECT switching speed slows down over cycling if IDS decreases (e, PE2 OE3OE3) but is stable if IDS is retained (f, PE2 OE4).
