Structural analysis of surfaces by LEED
TL;DR: The field of low energy electron diffraction (LEED) is reviewed with respect to its potential to surface structure determination in this article, where the present status of both theory and experiment is described.
Journal ArticleDOI
Directed search methods for surface structure determination by LEED
TL;DR: In this article, an automatic optimisation procedure for LEED was presented, which combines the complementary techniques of Tensor LEED and a numerical search algorithm, for the determination of two surface structures: clean Pd(111) and 3 × 3 R30°-CO.

Helium-atom-scattering study of the structure and phonon dynamics of the W(001) surface between 200 and 1900 K.
TL;DR: High-resolution helium-atom-scattering measurements of angular distributions and time-of-flight spectra are reported for W(001) in the temperature range from 200 to 1900 K, showing a reconstruction related superstructure peak whose angular position and intensity are temperature dependent.
Journal ArticleDOI
Charge-density waves on metal surfaces
TL;DR: In this paper, the Peierls-type charge-density-wave (CDW) transition on metal surfaces is reviewed based on the theoretical and experimental works on such transitions in bulk quasi-low-dimensional materials, two prototypical examples are presented.
Journal ArticleDOI
The clean and H-induced reconstruction of W(100) studied by LEED at slanting primary bean incidence
TL;DR: In this article, a new LEED study of the clean and hydrogen induced c(2×2) reconstruction of W(100) was presented, which showed that the LEED intensity analysis for data taken at sufficiently oblique incidence (θ≈74°) provides high sensitivity for surface parallel parameters without loosing that for coordinates normal to the surface.

A reliability factor for surface structure determinations by low-energy electron diffraction

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.

The clean thermally induced W {001} (1 × 1) → (√2 × √2) R 45° surface structure transition and its crystallography
M.K. Debe,David A. King +1 more
TL;DR: In this paper, it was shown that the (1 × 1) → (√2 × √2) R45° surface structure is a transition involving displacement of surface W atoms, and that it apparently can be characterized as an order-order, second degree, homogeneous nucleation process, which is strongly prohibited by the presence of impurities or defects.

Surface structures of W(110) and W(100) faces by the dynamical LEED approach
M. A. Van Hove,S. Y. Tong +1 more
TL;DR: In this article, the surface structures of W(110) and W(100) faces were examined by means of an efficient dynamical LEED method, and it was found that the W (110) surface maintains the bulk structure, despite the possibility for the top tungsten atoms to settle into sites of higher coordination number.
