Gigahertz Resonance at gold surface as a tool for ions study under polarized electric fields

Abstract

The Gigahertz Resonance at a gold nano-layer, coupled with an Electrochemical system allowed the investigation of the interfacial interaction of ions at the gold/aqueous solution boundary. The implications of the ion behavior under polarized electric fields are discussed. The study of non-Faradaic and Faradaic currents open the path for increased versatility as sensing device.
