Abstract

Numerical resolution of Poisson-Boltzmann’s equation has been carried out to determine the charge distribution induced by a strong static electric field just within the surface of a metal. This distribution has been fitted by an analytical model and then introduced in the wave equation of the light-electric field. The resolution of this last equation with the help of the Fourier transform gives the optical surface impedance of the metal as a function of the excess surface charge σ. The logarithmic derivative of the reflectance with respect to σ is then calculated and successfully compared to the experimental electroreflectance spectrum for the (111) face of a gold single crystal at the potential of zero charge.
