摘要：

We apply a microscopic formulation to calculate the second harmonic spectra of Si(100) 2 x 1. We compare the calculated second harmonic radiated efficiency for several 2 x 1 reconstructions, with different dimer bucklings, with each other. Besides the surface-allowed E-1, E-2 and E-1' resonances, other resonances at lower energies are found and explained in terms of transitions across surface states. We find that the spectra are dominated by the X-parallel to parallel to perpendicular to(s) component of the second-order surface susceptibility.
