title = "Ion scattering study of reconstruction in the Au(110)-(1×2) surface",
abstract = "Structural models for the clean Au(110)-(1 × 2) surface have been evaluated by comparison of calculations to experimental He+ backscattering surface yield measurements. Angular scans of the surface yield around the [101] and [100] off-normal axes are asymmetric. These results are in reasonable agreement with missing row surface models incorporating lateral translations in the second row and either an expansion or contraction of the top layer. Energy scans of the on-axis surface yield are consistent with these results. Lack of agreement between the experimental and calculated widths of the angular scans indicate that the structure models do not completely describe the surface.",

note = "Funding Information: The clean (110) surface of Au exhibits an atomic reconstruction with respect to the bulk termination lattice characterized by a doubling of the lattice periodicity in the \[001\]d irection. Several surface structures have been proposed to account for this. It is generally believed the most probable structure involves the absence of every other \[110\] atomic row in the surface layer, the {"}missing row{"} model. Early investigations ruled out the simple missing row model in which all surface layer atoms are at bulk lattice sites \[1-3\]. Hence, reconstruction involving displacements normal and/or parallel to the surface must be considered. A missing row model \[3\]i ncorporating a 17% contraction of the top layer spacing has been proposed on the basis of low energy electron diffraction (LEED). Helium diffraction results \[4\]a re in qualitative agreement with this top layer contraction. Low energy ion scattering experiments \[5,6\] suggest a contraction model with lateral translations in the second layer. However, X-ray diffraction data \[7\]s upport a structure model involving a large top layer expansion of approximately 40 + 30% and predict with high precision a pairing of \[110\] rows in the second layer.
