Abstract
The cleaved Si(111)-(2×1) surface is proposed to have two distinct structures with chainlike and molecular types of bonding, respectively. The two structures give rise to similar five- and sevenfold rings of atoms at the surface. The occurrence in varying proportions of both bonding configurations provides a natural explanation for the well-known cleavage-dependent properties of the Si(111) surface.
