โœฆ Synopsis

Optical second harmonic generation on sllvet electrode surfaces is shown to be highly sxxsitive to surface morphology at potentials within the double layer char&g region. S&,ht alterations in the surface strocture result in the appearance of a strong potential~ependent SH si@xil at biases nc@ive to the potent& of zero charge_ As observed in previous studies on smooth silver electrodes, this signal is strongly affected by anion adsorption on the surface.

Adsorption of anions on single crystal and polycrystalline silver surfaces has been monitored with optical second harmonic generation. Potentials investigated were restricted to the range between solvent reduction and the onset of metal osidation. Excess charge density on the metal surface is conclu

Optical second-harmonic generation has been used to follow in situ the growth of thin Ag รlms deposited on Si(111) under various substrate conditions and temperatures. This method is particularly sensitive to the microscopic structure of the deposited Ag รlms. Thus, island formation is found to enha
