Abstract Au (991) — a vicinal Au(110) surface with (111) steps parallel to the close-packed rows and a terrace width that can accommodate two missing rows — has been investigated with scanning tunneling microscopy and low energy electron diffraction. Irrespective of the annealing temperature (600–800 K) Au(991) stabilizes with small domains of Au(991)1 × 2). Predominant single step height as well as many kinks along [110] confirm that the reconstruction process proceeds mainly by movement in the MR direction. In addition, extended regions of Au(551)(1 × 2) are found indicating that Au(551) may be one of the “magically” stable vicinal surfaces.
