In Figure -e the results of the Bode plots are depicted using gate Ubias of -1, 0, and 1 V while an input voltage to the W-Cap of 0 ± 0.1 V is applied at the frequency range of interest from 10 mHz to 1 kHz. From the large positive phase shift of ~90° it can be clearly seen that at high frequencies the inductor is dominant, while at low frequencies the phase shift drops below 0°, thus entering the capacitor dominated regime. While the course of the graph for the inductively dominated frequency region is similar, the capacitive region for the 1 and -1 V case clearly differ. Due to the small capacitance of the blocked direction (1 V gate Ubias graph), the dominating capacitive behavior can be obtained already at higher frequencies reaching an fR of 91 Hz. According to Equation , this corresponds to an effective capacitance of 1.02 µF. Due to diffusive resistances at very low frequencies caused by the ion diffusion from the bulk electrolyte to the limited outer surface area of the sieving carbon, the phase shift is again approaching 0°, thus becoming ohmic again. For the -1 V gate Ubias (high capacitance, open direction), the system reached the capacitance-dominated region at significantly lower frequencies at a fR value of 71 Hz due to the high achievable capacitance at the -1 V gate Ubias (capacitor needs a longer time to fully charge). Therefore, over a long frequency range the phase angle is mainly stable at low negative phase angles more similar to an ohmic resistor than a capacitor. According to Equation 2, a fR of 71 Hz corresponds to an theoretical effective EDL capacitance of 2.37 µF at this frequency which is over 2 times higher compared to the value in the blocked direction.
