A multislice theory is proposed to solve Yoshioka's coupling equations for elastic and inelastic scattered high-energy electrons in a solid. This method is capable, in principle, of including the non-periodic crystal structures and the electron multiple scattering among all the excited states in the calculations. It is proved that the proposed theory for calculating the energy-filtered inelastic images [Wang (1989). Acta Cryst. A45, 193-199], based on the physical optics approach, is equivalent to the quantum-mechanical theory under some approximations. The basic theory of simulating the energy-filtered inelastic image of core-shell losses and thermal diffuse scattering is outlined.read more

TL;DR: A generalized multislice theory is employed to simulate the annular dark field (ADF) images, in scanning transmission electron microscopy (STEM), taking into account the inelastic thermal diffuse scattering (TDS).

TL;DR: An expression for the Fourier coefficients of the absorptive potential due to electron-impact ionization in crystals is derived and the cross section is given in terms of these Fourier components.

Correlations in space and time and dynamical diffraction of high-energy electrons by crystals.
TL;DR: It is proved that if the energy of an electron is sufficiently high (E∼100 ReV), the problem of multiple elastic and inelastic scattering by a solid is entirely determined by two universal functions.

Thickness effects in ADF STEM zone axis images
Sean Hillyard,John Silcox +1 more
TL;DR: In this article, the lattice fringe intensities in annular dark field scanning transmission electron microscope images of (100) indium phosphide were measured and it was shown that reasonable partial coherence effects give rise to serious limitations on imaging at the highest resolution levels.

Inelastic scattering of high-energy electrons in real space
Wim M. J. Coene,D. Van Dyck +1 more
TL;DR: In this article, the propagation of elastic and inelastic electron waves in high-energy electron diffraction in a thin crystal foil is described in a real-space framework and the imaginary absorption potential for single-electron excitation can be computed for each atom individually, independent of the crystal structure and the accelerating voltage.
