Abstract
Tunneling images of vicinal Si(001) tilted 4° about the [11¯0] direction have been obtained. Straight double steps running along the [11¯0] direction, separated by terraces of relatively uniform width, dominate the topography of the surface. The structure of the bi- atomic steps is best described by a model that involves a rebonded geometry with buckling.Keywords
