As a result of the potential shifts, a clear current increase in the CV curve can be observed when a Ubias is applied (Figure ) causing deliberate control of RRI. To understand this abrupt current and capacitance increase, the device was cycled without Ubias, with a Ubias of 0 V, and without Ubias but GE and CE directly interconnected as one electrode (Figure ). Interestingly when 0 V Ubias is applied, the CV curve of the W-Cap shows a very similar current response and shape as when the W-Cap is measured without applied Ubias but GE and CE are directly connected. Consequently, by applying a Ubias the capacitance of the GE seems to be "added" to the capacitance of CE due to its indirect connection in the measuring setup (CE and GE are balancing the charge on the WE together during their symmetrical cycling). As stated before, the W-Cap (CAPode) system with the chosen geometrical area ratio of Cmicro-Cmeso is unbalanced meaning the Cmicro electrode has a higher capacitance than the Cmeso electrode. By "adding" additional geometrical area from the GE, the CE (Cmeso electrode) has a similar achievable capacitance to WE (Figure ). Therefore, the charge carriers adsorbed on the WE can be balanced by the CE + GE combination. Consequently, the current response in the charging direction can be additionally controlled depending on the chosen balancing factors between WE and CE of the W-Cap as well as the electrode area of GE that can be "added" to the CE immediately after biasing to compensate the charge stored at WE. For a better visualization, the individual CV curves of WE and CE (obtained for the calculation method described by Slesinski et al. ) at three different bias conditions (no Ubias, low (-0.1 V), and high (-1 V)) for interdigital structure 1 (IDS1;Cmeso as a GE) are depicted in Figure .
