The diffusion of adatoms on Au(110) was studied via molecular dynamics simulation. The (1x1) and the missing-row (2x1) geometries were considered. In both geometries the diffusion was strongly anisotropic, because the energy barriers for cross-channel mobility were higher than the barriers for in-channel diffusion. In the (2x1) geometry, the adatom may diffuse not only by jumping on a straight line along the [1¯10] direction, but also by a random walk among the metastable sites on the (111) facets of the channel.
