a Schematic illustration of the OECT structure with patterned Au source (S)-drain (D) electrodes and electrodeposited PEDOT channel film. b Chemical structure of PEDOT+, PSS− and ClO4−. SEM (c–e) and AFM (f–h) images of PEDOT:ClO4 films electropolymerized at charge densities of: c, f 20 mC/cm2, d, g 30 mC/cm2 and e, h 60 mC/cm2. Yellow dashed lines: OECT channel. Red dashed box: region from which the surface roughness Rq is extracted.
