Figure 2. Impedance, resistance, and reactance at 1 kHz in log scale of raised Pt, recessed Pt and raised Au electrodes.

(a)-(b) Corrected impedance of raised Pt (a) and recessed Pt (b) electrodes, slope of linear fits for all but two smallest electrodes are shown in dash line, a guideline with a slope of −1 is also shown (dot-dash line). (c) Corrected impedance of raised Au electrodes, slope of linear fit for all electrodes is shown in dash line. (d)-(f) Corrected resistance of raised Pt (d), recessed Pt (e), and raised Au (f) electrodes, slope of linear fits for all but three largest electrodes are shown in dash line. (g)-(h) Corrected reactance of raised Pt (g) and recessed Pt (h) electrodes, slope of linear fit for all but two smallest electrodes is shown in dash line. (i) Corrected reactance of raised Au electrodes, slope of linear fit for all electrodes is −1.86 (dash line). The slope values are shown in the Table 1.
