Electron Microscopy In Material Science

Analytical electron microscopy is one of the most powerful tools today for characterization of the advanced materials that support the nanotechnology of the twenty-first century. In this book the authors clearly explain both the basic principles and the latest developments in the field. In addition to a fundamental description of the inelastic scattering process, an explanation of the constituent hardware is provided. Standard quantitative analytical techniques employing electron energy-loss spectroscopy and energy-dispersive X-ray spectroscopy are also explained, along with elemental mapping techniques. Included are sections on convergent beam electron diffraction and electron holography utilizing the field emission gun. With generous use of illustrations and experimental data, this book is a valuable resource for anyone concerned with materials characterization, electron microscopy, materials science, crystallography, and instrumentation.

Electron Microscopy in Material Science covers the proceedings of the International School of Electron Microscopy held in Erice, Itsaly, in 1970. The said conference is intended to the developments of electron optics and electron microscopy and its applications in material science. The book is divided into four parts. Part I discusses the impact of electron microscopy in the science of materials. Part II covers topics such as electron optics and instrumentation; geometric electron optics and its problems; and special electron microscope specimen stages. Part III explains the theory of electron diffraction image contrast and then elaborates on related areas such as the application of electron diffraction and of electron microscopy to radiation; computing methods; and problems in electron microscopy. Part IV includes topics such as the transfer of image information in the electron microscope; phase contrast microscopy; and the magnetic phase contrast. The text is recommended for electron microscopists who are interested in the application of their field in material science, as well as for experts in the field of material science and would like to know about the importance of electron microscopy.

Electron microscopy has revolutionized our understanding the extraordinary intellectual demands required of the mi of materials by completing the processing-structure-prop croscopist in order to do the job properly: crystallography, erties links down to atomistic levels. It now is even possible diffraction, image contrast, inelastic scattering events, and to tailor the microstructure (and meso structure ) of materials spectroscopy. Remember, these used to be fields in them to achieve specific sets of properties; the extraordinary abili selves. Today, one has to understand the fundamentals ties of modem transmission electron microscopy-TEM of all of these areas before one can hope to tackle signifi instruments to provide almost all of the structural, phase, cant problems in materials science. TEM is a technique of and crystallographic data allow us to accomplish this feat. characterizing materials down to the atomic limits.

High-resolution electron microscopy (HREM) has become a most powerful method for investigating the internal structure of materials on an atomic scale of around 0.1 nm. The authors clearly explain both the theory and practice of HREM for materials science. In addition to a fundamental formulation of the imaging process of HREM, there is detailed explanation of image simulationindispensable for interpretation of high-resolution images. Essential information on appropriate imaging conditions for observing lattice images and structure images is presented, and methods for extracting structural information from these observations are clearly shown, including examples in advanced materials. Dislocations, interfaces, and surfaces are dealt with, and materials such as composite ceramics, high-Tc superconductors, and quasicrystals are also considered. Included are sections on the latest instruments and techniques, such as the imaging plate and quantitative HREM.
