Bode and Bode phase plots of UNCD microelectrodes: 250-μm (black), 200-μm (green), 150-μm (brown), 100-μm (orange), 50-μm (red), 25-μm (gray) and 10-μm (purple). The solid curves are fitted to the experimental data. The electrolyte is 5 mM in 1 M KCl. The inset shows the SEM image of MCD microelectrode surface. The scale bar is 1-μm.
