| Research Abstract |
As the first step for understanding dipole-dipole interaction among molecules on a solid surface, we observed Sum Frequency Generation (SFG) spectra of H-Si(111)1×1 surface with coverage reduction. As the results, the peak positions of SFG spectra attributed to Si-H stretching vibration were red-shifted, and the widths of them were broadened with the coverage reduction. The red-shifted peak positions were well consistent with those calculated by theory of dipole-dipole interaction. However, the width broadening were not well consistent with the calculated those, and thus those may be attributed to local structure defects or effects of neighbor dangling bonds.
