Available in PDF, EPUB and Kindle. Book excerpt: The single scattering contribution of the low-energy electron diffraction (LEED) intensity has been extracted by an averaging technique. This allows analysis using only simple modifications of conventional diffraction analysis. Very detailed checks of the procedure have been made for clean surfaces of Ni(111), Ag(111) and W(110). The experimentally averaged intensities agrees with the calculated single scattering intensity to within a few percent. In order to study the effects of lattice dynamics a very accurate diffractometer was built to operate from 8 to 1000K. Thermal diffuse scattering of elecrons from Ag were studied and separated into zero, one, and multiphonon scattering events throughout the entire Brillouin zone. This work also makes it possible to account for the thermal scattering sufficiently accurately to study disordered overlayers and surface imperfections on solids. Physisorption of Xe on Ag(111) and chemisorption of O on W were studied.

Available in PDF, EPUB and Kindle. Book excerpt: Surface crystallography plays the same fundamental role in surface science which bulk crystallography has played so successfully in solid-state physics and chemistry. The atomic-scale structure is one of the most important aspects in the understanding of the behavior of surfaces in such widely diverse fields as heterogeneous catalysis, microelectronics, adhesion, lubrication, cor rosion, coatings, and solid-solid and solid-liquid interfaces. Low-Energy Electron Diffraction or LEED has become the prime tech nique used to determine atomic locations at surfaces. On one hand, LEED has yielded the most numerous and complete structural results to date (almost 200 structures), while on the other, LEED has been regarded as the "technique to beat" by a variety of other surface crystallographic methods, such as photoemission, SEXAFS, ion scattering and atomic diffraction. Although these other approaches have had impressive successes, LEED has remained the most productive technique and has shown the most versatility of application: from adsorbed rare gases, to reconstructed surfaces of sem iconductors and metals, to molecules adsorbed on metals. However, these statements should not be viewed as excessively dogmatic since all surface sensitive techniques retain untapped potentials that will undoubtedly be explored and exploited. Moreover, surface science remains a multi-technique endeavor. In particular, LEED never has been and never will be self sufficient. LEED has evolved considerably and, in fact, has reached a watershed.

This book was released on 2012-12-06 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at the NATO Advanced Research Workshop in "Reflection High Energy Electron Diffraction and Reflection Electron Imaging of Surfaces" held at the Koningshof conference center, Veldhoven, the Netherlands, June 15-19, 1987. The main topics of the workshop, Reflection High Energy Electron Diffraction (RHEED) and Reflection Electron Microscopy (REM), have a common basis in the diffraction processes which high energy electrons undergo when they interact with solid surfaces at grazing angles. However, while REM is a new technique developed on the basis of recent advances in transmission electron microscopy, RHEED is an old method in surface crystallography going back to the discovery of electron diffraction in 1927 by Davisson and Germer. Until the development of ultra high vacuum techniques in the 1960's made instruments using slow electrons more accessable, RHEED was the dominating electron diffraction technique. Since then and until recently the method of Low Energy Electron Diffraction (LEED) largely surpassed RHEED in popularity in surface studies. The two methods are closely related of course, each with its own specific advantages. The grazing angle geometry of RHEED has now become a very useful feature because this makes it ideally suited for combination with the thin growth technique of Molecular Beam Epitaxy (MBE). This combination allows in-situ studies of freshly grown and even growing surfaces, opening up new areas of research of both fundamental and technological importance.

Available in PDF, EPUB and Kindle. Book excerpt: Low-energy electron diffraction offers the potential for surface crystallography analogous to x-ray and neutron studies of the bulk. This potential has not been fully realized because of the strong interactions, both elastic and inelastic, between the electron and the crystal. The report summarizes experiments done in an effort to achieve sufficient understanding of the diffraction to realize this potential. Studies on the scattering from Ni at high temperatures and from liquid Hg established that: (1) the atomic scattering factor for backward scattering is essentially the same for free atoms and those in the condensed phase; (2) multiple scattering processes are strongly attenuated by inelastic processes; (3) roughly half the elastically back scattered electrons have interacted only once; (4) penetration depths are the order of 1-3 atomic spacings. Other studies establish quantitatively a two step process for the inelastic scattering for small energy losses and allow determination of the loss function and show that the surface loss contributions are dominant. Careful studies as a function of T and all the diffraction variables have determined detailed properties of the elastic scattering from Ag(111) and Ni(111) including the azimuthal symmetry, Debye Waller factors as a function of energy, effective thermal expansion.

This book was released on 2022-06-30 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely text covers the theory and practice of surface and nanostructure determination by low-energy electron diffraction (LEED) and surface X-ray diffraction (SXRD): it is the first book on such quantitative structure analysis in over 30 years. It provides a detailed description of the theory, including cutting-edge developments and tested experimental methods. The focus is on quantitative techniques, while the qualitative interpretation of the LEED pattern without quantitative I(V) analysis is also included. Topics covered include the future study of nanoparticles, quasicrystals, thermal parameters, disorder and modulations of surfaces with LEED, with introductory sections enabling the non-specialist to follow all the concepts and applications discussed. With numerous colour figures throughout, this text is ideal for undergraduate and graduate students and researchers, whether experimentalists or theorists, in the fields of surface science, nanoscience and related technologies. It can serve as a textbook for graduate-level courses of one or two semesters.
