This folder contains raw data for Supplementary Information Figure S4.

The respective text files contain raw data for the coulometric titration experiment on an Au interlayer, on an Ag interlayer and on a Bi interlayer. All data is unnormalized. For the sake of completeness, the electrode Diameter is given in each Header of the text file. Please note that after each titration cycle, an impedance measurement was conducted. For easier understanding, the cycle number is given in the first column of each text file.
