This book was released on 1990 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray microanalysis by analytical electron microscopy (AEM) has proven to be a powerful tool for characterizing the spatial distribution of solute elements in materials. True compositional variations over spatial scales smaller than the actual resolution for microanalysis can be determined if the measured composition profile is deconvoluted. Explicit deconvolutions of such data, via conventional techniques such as Fourier transforms, are not possible due to statistical noise in AEM microanalytical data. Hence, the method of choice is to accomplish the deconvolution via iterative convolutions. In this method, a function describing the assumed true composition profile, calculated by physically permissible thermodynamic and kinetic modeling, is convoluted with the x-ray generation function and the result compared to the measured composition profile. If the measured and calculated profiles agree within experimental error, it is assumed that the true compositional profile has been determined. If the measured and calculated composition profiles are in disagreement, the assumptions in the physical model are adjusted and the convolution process repeated. To employ this procedure it is necessary to calculate the x-ray generation function explicitly. While a variety of procedures are available for calculating this function, the most accurate procedure is to use Monte Carlo modeling of electron scattering.

Download or read book Transport of Energetic Electrons in Solids written by Maurizio Dapor and published by Springer Nature. This book was released on 2023-09-11 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the computational methods most frequently used to deal with the interaction of charged particles, notably electrons, with condensed matter. Both elastic and inelastic scattering phenomena are discussed, and methods for calculating the relevant cross sections are explained in a rigorous but simple way. It provides readers with all the information they need in order to write their own Monte Carlo code and to simulate the transport of fast particles in condensed matter. Many numerical and experimental examples are presented throughout the book. The updated and extended fourth edition features ab initio methods for calculating dielectric function and energy loss function. Non-relativistic partial wave expansion method for calculating the differential elastic scattering cross section is also included in this new edition. It represents a very useful introduction to the relativistic partial wave expansion method, i.e., to the Mott theory, already discussed in the previous editions of this book. Further details about the effects of spin-polarization on the differential elastic scattering cross section are included in this new edition. The multiple reflection method is extended to the general case of a system composed of a set of layers of different materials and thicknesses. Analytical expressions are provided for calculating the backscattering coefficient of multilayers. New results are presented, notably about Monte Carlo simulations of reflection electron energy loss spectra and of the radial dose deposited along the track of ions impinging on materials.
