μe,OECT OECT saturation mobility and threshold voltage (Vth) extracted from fits of Id1/2 vs VG plots.
C* average volumetric capacitance beyond the Vth determined by electrochemical impedance spectroscopy. Reported uncertainties are one standard deviation, with n = 6 devices.
μC* extracted from the slope of saturated transfer curves at −0.6 V.
