摘要：

The scanning-tunneling-microscope (STM) topographies taken from a N-induced (2 X 3) reconstructed Cu(110) surface provide unique information, which offers the basis for an explanation of the peculiar fact that every third <110> row is missing and also confirm in detail the structural model inferred from recent ion-scattering measurements. The close analysis of STM images with atomic resolution taken from both ordered (2 X 3) domains and local defective arrangements evidences the existence of long-range, highly directional interactions between Cu - N - Cu bonds, which seems to determine ultimately the nature of the reconstruction.
