Electroreflectance spectra of Ag(111) electrodes

摘要: Abstract Electroreflectance (ER) spectra of Ag(111) evaporated electrodes on mica in aqueous electrolytes were measured within the wavelength range 500 to 200 nm for p- and s-polarized light as a function angle incidence, bias potential surface roughness. These show structures which not seen previously obtained ER slightly rough, polycrystalline Ag electrodes. The effect volume plasma excitation is clearly indicated. experimental results cannot be reproduced satisfactorily by any currently employed theoretical model takes only free electron effects into account. influence electric field bound electrons layer obviously neglected. It demonstrated that resonance shifted energy applied field.
