To examine the influence of the GE material and its capacitance on the shifting ability of the W-Cap, a G-Capode with the structure IDS2 (Figure ) was designed using a Ti-mesh with a very low capacitance of 0.3 mF cm -2 (calculated from a symmetric Ti-mesh EDLC with similar geometric area like IDS2) (Figure ) as GE material. Again, stepwise negative and positive Ubias are applied (Figure ).
