Abstract
The surface-phonon structure of a simple model of fcc crystal dynamics is studied. The surfaces consist of wide (111) terraces separated by periodic, monatomic steps. A new class of vibrational mode is found. In addition to being localized to the surface like normal surface phonons, these modes are also localized along the step edges.Keywords
