TLDR
Theoretical motivations for multilayer relaxation in relatively simple metallic surfaces are reviewed in this paper, and results from LEED analyses are presented which serve to demonstrate that multillayer relaxation measurably exists in Cu(100) and Cu(110) surfaces.About:

Simple N-body potentials for the noble metals and nickel
TL;DR: In this article, the N-body potentials for copper, silver, gold, and nickel have been constructed using the approach of Finnis and Sinclair, where the total energy is regarded as consisting of a pairpotential part and a many body cohesive part.
Journal ArticleDOI
Ion beam crystallography of surfaces and interfaces
TL;DR: The current status of Rutherford Backscattering Spectrometry (RBS) of surfaces and interfaces is reviewed in this article, along with a variety of Monte Carlo methods for computer simulation of the shadowing and blocking experiments.

Multilayer distortion in the reconstructed (110) surface of Au
Wolfgang Moritz,D. Wolf +1 more
TL;DR: A new LEED intensity analysis of the reconstructed Au(110)-(1×2) surface results in a modification of the missing row model with considerable distortions which are at least three layers deep.

Surface and bulk properties of metals modelled with Sutton-Chen potentials
TL;DR: In this article, the semi-empirical many-body potentials of Sutton and Chen have been determined for face-centered-cubic surface models of face centered cubic metals, and the (1 × 2) reconstruction of the (110) surface is predicted to be energetically stable for platinum and gold and not for other metals.

Multilayer relaxation and surface energies of fcc and bcc metals using equivalent crystal theory
TL;DR: In this article, the multilayer relaxation of fcc and bcc metal surfaces is calculated using equivalent crystal theory and the results for changes in interplanar spacings of planes close to the surface are discussed in reference to other theoretical results and compared to available experimental data.

A reliability factor for surface structure determinations by low-energy electron diffraction
E. Zanazzi,F. Jona +1 more
TL;DR: In this article, a reduced r -factor r r = r r random where r random is the average value of r for randomly chosen pair of curves is calculated for more than 100 beams from 7 different surface structures and a direct relationship is established between the language of visual evaluation and numerical values of r ϵ.

Theory of lattice contraction at aluminium surfaces
Michael W. Finnis,Volker Heine +1 more
TL;DR: In this paper, the elementary concepts which govern the bulk total energy and crystal structure of sp bonded metals are also relevant at the surface, and a simple model explains the observed contraction in the interlayer spacing of the (110) surface layer of aluminium compared with the (100) and (111) surfaces.

Surface structure refinements of 2HMoS2, 2HNbSe2 and W(100)p(2 × 1)O via new reliability factors for surface crystallography
TL;DR: In this paper, the authors define five reliability factors (R-factors) which evaluate the reliability of a given surface structure analysis by calculating numerical values based on the degree of agreement between calculated and measured low-energy electron diffraction (LEED) intensity-voltage (I-V ) curves.

The surface structure of V(100)
TL;DR: In this article, the structure of the clean V(100)−(1×1) surface is determined, based on an r-factor comparison of experimental LEED intensity-energy spectra with the results of multiple-scattering model calculations.
