Abstract

Spectroscopic second-harmonic generation (SHG) and reflectance-anisotropy spectroscopy are used to probe a single-domain reconstructed stepped Si(001) surface off cut 6° toward [110] before and after dissociative adsorption of H2 at the DB step edges. The reflectance-anisotropy spectrum and the first- and third-order Fourier components of the SHG azimuthal anisotropy exhibit broad step-induced resonant peaks near 3.1 eV that are quenched in approximate proportion to H2 dosage, suggesting that they all share a common origin in the essential electronic resonance of the DB steps. Analysis with a simplified bond-hyperpolarizability model suggests that hydrogen termination redistributes oscillator strength from the chemically active nearly vertical step dangling bond into three underlying bonds, suggesting the latter may be related to the third-order Fourier component of the SHG response.
