Abstract

A model for a second harmonic generation (SHG) at the metal/electrolyte interface is proposed and treated by an electron density functional calculation. The dependence of the SHG signal on the electrode charge, σ, is studied for different values of system parameters which represent different aspects of metal-medium interaction. Characteristic differences between the SHG signal at a free metal surface and at the same metal in contact with an electrolyte are predicted in the range of negative charges and near the zero charge point. "Fundamental" trends in the signal changes upon ionic adsorption are established.
