Book Description
In the modern world of ever smaller devices and nanotechnology, electron crystallography emerges as the most important method capable of determining the structure of minute objects down to the size of individual atoms. Crystals of only a few millionths of a millimetre are studied. This is the first textbook explaining how this is done. Great attention is given to symmetry in crystals and how it manifests itself in electron microscopy and electron diffraction, and how this symmetry can be determined and taken advantage of in achieving improved electron microscopy images and solving crystal structures from electron diffraction patterns. Theory and practice are combined; experimental images, diffraction patterns, formulae and numerical data are discussed in parallel, giving the reader a complete understanding of what goes on inside the "black boxes" of computer programs. This up-to-date textbook contains the newest techniques in electron crystallography, including detailed descriptions and explanations of the recent remarkable successes in determining the very complex structures of zeolites and intermetallics. The controversial issue of whether there is phase information present in electron micrsocopy images or not is also resolved once and for all. The extensive appendices include computer labs which have been used at various courses at Stockholm University and international schools in electron crystallography, with applications to the textbook. Students can download image processing programs and follow these lab instructions to get a hands-on experience of electron crystallography.

Book Description
Crystallographic texture or preferred orientation has long been known to strongly influence material properties. Historically, the means of obtaining such texture data has been though the use of x-ray or neutron diffraction for bulk texture measurements, or transmission electron microscopy or electron channeling for local crystallographic information. In recent years, we have seen the emergence of a new characterization technique for probing the microtexture of materials. This advance has come about primarily through the automated indexing of electron backscatter diffraction (EBSD) patterns. The first commercially available system was introduced in 1994, and since then of sales worldwide has been dramatic. This has accompanied widening the growth applicability in materials scienceproblems such as microtexture, phase identification, grain boundary character distribution, deformation microstructures, etc. and is evidence that this technique can, in some cases, replace more time-consuming transmission electron microscope (TEM) or x-ray diffraction investigations. The benefits lie in the fact that the spatial resolution on new field emission scanning electron microscopes (SEM) can approach 50 nm, but spatial extent can be as large a centimeter or greater with a computer controlled stage and montagingofthe images. Additional benefits include the relative ease and low costofattaching EBSD hardware to new or existing SEMs. Electron backscatter diffraction is also known as backscatter Kikuchi diffraction (BKD), or electron backscatter pattern technique (EBSP). Commercial names for the automation include Orientation Imaging Microscopy (OIMTM) and Automated Crystal Orientation Mapping (ACOM).

Book Description
Topics in Electron Diffraction and Microscopy of Materials celebrates the retirement of Professor Michael Whelan from the University of Oxford. Professor Whelan taught many of today's heads of department and was a pioneer in the development and use of electron microscopy. His collaborators and colleagues, each one of whom has made important advances in the use of microscopy to study materials, have contributed to this cohesive work. The book provides a useful overview of current applications for selected electron microscope techniques that have become important and widespread in their use for furthering our understanding of how materials behave. Linked through the dynamical theory of electron diffraction and inelastic scattering, the topics discussed include the history and impact of electron microscopy in materials science, weak-beam techniques for problem solving, defect structures and dislocation interactions, using beam diffraction patterns to look at defects in structures, obtaining chemical identification at atomic resolution, theoretical developments in backscattering channeling patterns, new ways to look at atomic bonds, using numerical simulations to look at electronic structure of crystals, RHEED observations for MBE growth, and atomic level imaging applications.

The role of diffraction methods for the solid-state sciences has been pivotal to determining the (micro)structure of a material. Particularly, the expanding activities in materials science have led to the development of new methods for analysis by diffraction. This book offers an authoritative overview of the new developments in the field of analysis of matter by (in particular X-ray, electron and neutron) diffraction. It is composed of chapters written by leading experts on 'modern diffraction methods'. The focus in the various chapters of this book is on the current forefront of research on and applications for diffraction methods. This unique book provides descriptions of the 'state of the art' and, at the same time, identifies avenues for future research. The book assumes only a basic knowledge of solid-state physics and allows the application of the described methods by the readers of the book (either graduate students or mature scientists).

Book Description
Structure Analysis by Electron Diffraction focuses on the theory and practice of studying the atomic structure of crystalline substances through electron diffraction. The publication first offers information on diffraction methods in structure analysis and the geometrical theory of electron diffraction patterns. Discussions focus on the fundamental concepts of the theory of scattering and structure analysis of crystals, structure analysis by electron diffraction, formation of spot electron diffraction patterns, electron diffraction texture patterns, and polycrystalline electron diffraction patterns. The text then ponders on intensities of reflections, including atomic scattering, temperature factor, structure amplitude, experimental measurements of intensity, and review of equations for intensities of reflections in electron diffraction patterns. The manuscript examines the Fourier methods in electron diffraction and experimental electron diffraction structure investigations. Topics include the determination of the structure of the hydrated chlorides of transition metals; structures of carbides and nitrides of certain metals and semi-conducting alloys; electron diffraction investigation of clay minerals; and possibilities inherent in structure analysis by electron diffraction. The book is a helpful source of data for readers interested in structure analysis by electron diffraction.

Book Description
For many years, evidence suggested that all solid materials either possessed a periodic crystal structure as proposed by the Braggs or they were amorphous glasses with no long-range order. In the 1970s, Roger Penrose hypothesized structures (Penrose tilings) with long-range order which were not periodic. The existence of a solid phase, known as a quasicrystal, that possessed the structure of a three dimensional Penrose tiling, was demonstrated experimentally in 1984 by Dan Shechtman and colleagues. Shechtman received the 2011 Nobel Prize in Chemistry for his discovery. The discovery and description of quasicrystalline materials provided the first concrete evidence that traditional crystals could be viewed as a subset of a more general category of ordered materials. This book introduces the diversity of structures that are now known to exist in solids through a consideration of quasicrystals (Part I) and the various structures of elemental carbon (Part II) and through an analysis of their relationship to conventional crystal structures. Both quasicrystals and the various allotropes of carbon are excellent examples of how our understanding of the microstructure of solids has progressed over the years beyond the concepts of traditional crystallography.
