NUMERICAL INVESTIGATION OF THE PLASMA ELECTROREFLECTANCE MODEL AT LEAD AND INDIUM ELECTRODES.

The plasma electroreflectance mechanism is discussed for lead and indium electrodes in terms of microscopic theory of light reflection from metals. The calculation is performed for s- and p-polarized light. It is shown that the electroreflectance signal obtained in p-polarized light is determined, not only by the double-layer capacitance but also by the potential dependence of the characteristic length of electron density decay outside the metal. The results of the numerical calculations are compared with experimental data.
