Abstract :
We studied the vibrational structure of vicinal hydrogenated Si(1 1 1) surfaces by transmission infrared spectroscopy. In particular, we investigated the bending modes of the silicon hydrides present on the terraces and at the step-edges. We find that step-induced surface stress and/or long-range dipolar interactions split the bending modes of the Si(1 1 1) terrace monohydrides into two components, parallel and perpendicular to the step-edge direction.
