Similar observations can be made when a positive Ubias voltage is applied. By applying stepwise increasing positive Ubias voltages, the cut-off voltage and the whole working window of the W-Cap are shifted stepwise to more positive voltage values (Figure and). Similar to the previous observations, this shift in the cut-off voltage is increasing almost linearly with the applied increasing bias voltage (0.33 V shift/ 1 V applied Ubias), however the shifting is a little less pronounced compared to the negative cut-off voltage shift as described above. When positive Ubias are applied to GE, the potential of GE is shifted to more positive and the potential of CE to more negative values to fulfill the applied voltage difference. Again, the WE is following the potential shift of CE (to more negative values). Therefore, the working window of the whole W-Cap is shifted to more negative potential values leading to the observed shift of the entire CV curve. Interestingly, the working window of the CE is decreasing while the working window of WE is expanding with increasing positive Ubias. Due to the shift of the WE to more negative potentials, the blocked polarization direction is dominating the working window of the whole W-Cap causing an overpolarization of the WE to compensate the charge (small anions) accumulated on the Cmeso (CE) by stimulating an accumulation of the bulky cations on the limited outer surface of Cmicro (WE). The limited possible charge accumulation in the dominating blocking direction at high positive Ubias is also visible in the narrow working window of CE which automatically causes a limited working window of GE. This effect of overpolarizing the WE with increasing Ubias is hindering to some extent the shifting of the whole W-Cap CV curve and the cut-off voltage causing the above mentioned lower shifting ability of the W-Cap to positive voltage values.
