Abstract
The electrochemical behaviour and nonlinear optical properties of l-Cysteine on Ag(1 1 1) single crystal electrodes in a non adsorbing electrolyte have been investigated for the first time. l-Cysteine adsorbs on Ag(1 1 1) stronger than on Au(1 1 1) and is stable over a wider range of potential. Reduction/oxidation processes have been identified at potentials well below the potential of zero charge. The adsorption process at a controlled potential value has been followed by measurements of the second harmonic response, which mainly responds to the electronic changes produced at the interface by the formation of the Ag–S bond. The film formed on Ag(1 1 1) exhibits rather insulating properties in the potential region positive to the potential of zero charge.
