Anisotropic Standing-Wave Formation on an Au(111)-(23×3)Reconstructed Surface

Abstract
Significant effects of the long-range “herringbone” reconstruction on the formation of standing waves in the Fermi-level surface-state electron density were observed for the first time on an Au(111)- (23×3) reconstructed surface using a low-temperature scanning tunneling microscope at 30 K. Enhanced oscillation of the surface local density of states was observed, especially along the pairwise soliton walls, which suggests the possible existence of anisotropic wave propagation.
