NaF<? format?> solution. The interface width exceeds capillary wave theory predictions and
displays an anomalous dependence on the voltage applied across it, displaying a minimum
positive of the potential of zero charge. The latter is explained by electrocapillary effects and
an additional intrinsic broadening of the interface profile, tentatively assigned to polarization
of the conduction electrons due to the electric field of the electrochemical double layer at the …
