Abstract

Surface structures of submonolayer alkanethiol CH₃(CH₂)_n-1SH (n = 6,12) adsorbed on Cu(111) at room temperature (0.3 ML) were investigated by means of S K-edge surface extended X-ray absorption fine structure (EXAFS) and S, C K-edge near-edge X-ray absorption fine structure (NEXAFS) spectroscopies. Polarization dependence of the C K-edge NEXAFS spectra revealed that alkanethiol molecules adsorb with the tilt angle of 12 ± 10° from the surface normal. The S K-edge surface EXAFS determined that the S-Cu distance is 2.31 ± 0.02 Å and that the S atoms locate at a deep three-fold hollow site with significant lateral outward movements of the nearest neighbor Cu atoms.
