title: Surface analysis of materials in aqueous solution by localized alternating current impedance measurements.
abstract: Differences in electrical conductivity provide a basis for identification of different components present at a material surface. Here it is demonstrated that this effect can be exploited for surface analysis of compound materials in solution by making localized alternating current impedance measurements.
