(111) facets as the origin of reconstructed Au(110) surfaces

Abstract

The Au(110) surface has been investigated by scanning tunneling microscopy. The reconstructed surface consists of long ribbons of narrow (111) facets along the [110] direction with maximum three free rows. Two-row facets give rise to the 1 × 2 reconstruction of the missing-row type, while three-row facets account for the 1 × 3 reconstruction. Disorder arises from locally random sequences of the two facets. © 1983.
