| "First, we obtain linear and non-linear optical spectra of clean Si(100) 2x1 reconstructed surfaces based on the model of polarizable bonds. The crystal is is modeled as an array of point-like polarizable dipoles where each dipole is considered to be at the middle of every Si-Si bond. The model incorporates the reconstruction of the surface through the local field effect. We calculate the optical spectra as a function of dimer buckling and it is shown that the structure which nicely reproduce the experimental reflectance anisotropy and second harmonic generation (SHG) spectra for the c(4 X 2) Si(100) surface. On the other hand, we apply a microscopic formalism to calculate the different contribution to the nonlinear second-order susceptibility required in the calculation of SHG." | |
