Available in PDF, EPUB and Kindle. Book excerpt: Atomic resolution electron microscopy ranks as one of the most important characterization methods in materials science. Example applications range from investigating single defects to determining detailed interface reconstructions. In recent years, high-angle annular dark-field (HAADF) scanning transmission electron microscopy (STEM) has become the technique of choice because the image intensities are considered to be intuitively interpretable and depend sensitively upon the atomic species present. The combination of experiment with electron scattering theory would thus enable the extraction of chemical information directly from the images without the need for calibration standards. However, theoretical predictions of contrast in atomic resolution electron microscopy images have never agreed quantitatively with experiments, raising questions as to whether the current understanding of image formation in the electron microscope is adequate.

Download or read book Atom Probe Tomography written by Michael K. Miller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microanalytical technique of atom probe tomography (APT) permits the spatial coordinates and elemental identities of the individual atoms within a small volume to be determined with near atomic resolution. Therefore, atom probe tomography provides a technique for acquiring atomic resolution three dimensional images of the solute distribution within the microstructures of materials. This monograph is designed to provide researchers and students the necessary information to plan and experimentally conduct an atom probe tomography experiment. The techniques required to visualize and to analyze the resulting three-dimensional data are also described. The monograph is organized into chapters each covering a specific aspect of the technique. The development of this powerful microanalytical technique from the origins offield ion microscopy in 1951, through the first three-dimensional atom probe prototype built in 1986 to today's commercial state-of-the-art three dimensional atom probe is documented in chapter 1. A general introduction to atom probe tomography is also presented in chapter 1. The various methods to fabricate suitable needle-shaped specimens are presented in chapter 2. The procedure to form field ion images of the needle-shaped specimen is described in chapter 3. In addition, the appearance of microstructural features and the information that may be estimated from field ion microscopy are summarized. A brief account of the theoretical basis for processes of field ionization and field evaporation is also included.

This book was released on 2013-03-09 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characterisation of materials and material systems is an essential aspect of materials science. A few decades ago it became obvious that, because the properties of materials depend so critically on the microstructure of their components, this characterisation must be determined to the atomic level. This means that the position - as well as the nature - of individual atoms has to be determined at "critical" regions close to defects such as dislocations, interfaces, and surfaces. The great impact of advanced transmission electron microscopy (TEM) techniques became apparent in the area of semiconducting materials, where the nature of internal interfaces between silicon and the corresponding silicides could be identified, and the results used to enhance the understanding of the properties of the compounds studied. At that time, advanced TEM techniques existed predominantly in the US. However, advanced TEM instrumentation was not available in the ma terials science and solid-state science communities in Germany. This gap was bridged by the late Peter Haasen who, after a visit to the US, initiated a Priority Programme on Microstructural Characterisation at the Volkswagen Foundation (Hannover). The programme was in effect from 1985 to 1997 and supported a wide range of research projects - from fundamental, trendy, innovative projects to projects in applied materials science.

Download or read book Quantitative Scanning Transmission Electron Microscopy of Point Defects in Crystals written by Jie Feng and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three-dimensional characterization of defects is an essential step in the engineering of point defects to control the type, concentration, and spatial distribution of defects with nanometer-scale resolution to design materials with new functions and properties. High-resolution electron microscopy is becoming a general-purpose tool for characterizing several point defects with single-defect sensitivity and sub-unit cell spatial resolution in all three dimensions. Detectable defects include substitutional impurities, interstitial impurities, self-interstitials, and impurity-containing defect complexes. However, all the defects so far imaged at the single-defect level often increase the local electron scattering by 50% or more, and 3D imaging of defects that change column intensity less than 10%, such as single vacancies was only reported very recently. In the first part of this thesis, we demonstrated an approach for three-dimensional imaging of single vacancies using high precision quantitative high-angle annular dark-field Z-contrast scanning transmission electron microscopy. Vacancies are identified by both the reduction in scattered intensity created by the missing atom and the distortion of the surrounding atom positions. Vacancy positions are determined laterally to a unique lattice site in the image and in depth to within one of two lattice sites by dynamical diffraction effects. 35 single La vacancies are identified in images of a LaMnO3 thin film sample. The vacancies are randomly distributed in depth and correspond to a La vacancy concentration of 0.79%, which is consistent with the level of control of cation stoichiometry within our synthesis process (~1%) and with the equilibrium concentration of La vacancies under the film growth conditions. This method can be extended to detect other defects including impurities and defect clusters and these results represent a step forward in characterizing point defects in materials one at a time, at atomic resolution, matching our current capabilities in materials simulation and our growing control over defect distributions in synthesis. In the second parts of this thesis, I adapted the cut-edge Poisson denoising and machine learning algorithm into the four-dimensional STEM, which could potentially detect point defects that are undetectable by traditional STEM. We demonstrate that the iterative BM4D Poisson denoising algorithm could recover most of the image features corrupted by Poisson noise and increase the PSNR most. We also demonstrate that the convolutional neural network (VGG-16), trained on simulated PACBED data set, could accurately predict TEM sample thickness with> 99% accuracy within 100 nm with 2 nm thickness step.

This book was released on 2012-12-06 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Advanced Study Institute provided an opportunity for researchers in universities, industry and National and International Laboratories, from the disciplines ofmaterials science, physics, chemistry and engineering to meet together in an assessment of the impact of electron and scanning probe microscopy on advanced material research. Since these researchers have traditionally relied upon different approaches, due to their different scientific background, to advanced materials problem solving, presentations and discussion within the Institute sessions were initially devoted to developing a set ofmutually understood basic concepts, inherently related to different techniques ofcharacterization by microscopy and spectroscopy. Particular importance was placed on Electron Energy Loss Spectroscopy (EELS), Scanning Probe Microscopy (SPM), High Resolution Transmission and Scanning Electron Microscopy (HRTEM, HRSTEM) and Environmental Scanning Electron Microscopy (ESEM). It was recognized that the electronic structure derived directly from EELS analysis as well as from atomic positions in HRTEM or High Angle Annular Dark Field STEM can be used to understand the macroscopic behaviour of materials. The emphasis, however, was upon the analysis of the electronic band structure of grain boundaries, fundamental for the understanding of macroscopic quantities such as strength, cohesion, plasticity, etc.

This book was released on 2015-03-23 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aberration-Corrected Imaging in Transmission Electron Microscopy provides an introduction to aberration-corrected atomic-resolution electron microscopy imaging in materials and physical sciences. It covers both the broad beam transmission mode (TEM; transmission electron microscopy) and the scanning transmission mode (STEM; scanning transmission electron microscopy). The book is structured in three parts. The first part introduces the basics of conventional atomic-resolution electron microscopy imaging in TEM and STEM modes. This part also describes limits of conventional electron microscopes and possible artefacts which are caused by the intrinsic lens aberrations that are unavoidable in such instruments. The second part introduces fundamental electron optical concepts and thus provides a brief introduction to electron optics. Based on the first and second parts of the book, the third part focuses on aberration correction; it describes the various aberrations in electron microscopy and introduces the concepts of spherical aberration correctors and advanced aberration correctors, including correctors for chromatic aberration. This part also provides guidelines on how to optimize the imaging conditions for atomic-resolution STEM and TEM imaging.This second edition has been completely revised and updated in order to incorporate the very recent technological and scientific achievements that have been realized since the first edition appeared in 2010.
