    Abstract

    We describe measurements of the complex admittance of the interface between electrodeposited fractal electrodes and electrolytic solutions over the frequency range 100 Hz to 100 kHz. Scaling with a single size-dependent frequency collapses these data onto a universal curve. This scaling collapse provides quantitative support for the Halsey-Leibig theory for constant phase angle behavior and a technique for measuring the multifractal descriptors Df and (2) for such electrodes. [Df is the rough electrodes fractal dimension, and the multifractal exponent (2) is the correlation dimension of the surfaces harmonic measure.]
