摘要：

We apply a microscopic formulation to calculate the second harmonic spectra of Si(100) in the presence of surface localized de electric field. We find that the surface-allowed E-1 resonances for clean and H covered surfaces shift as a function of the de field in agreement with experiment. This suggests the presence of built-in electric fields whose strength depends on the H coverage, and which are strongly localized in the subsurface region.
