Dynamic Inelastic Electron Scattering III: Multislice Theory

Abstract

The multislice theory of elastic scattering theory was outlined in chapter 3. The unique advantage of this theory is its convenience of including defects in computations. The equivalent method has been applied to calculate the scattering of inelastic electrons in crystals. In this chapter we first illustrate the multislice solution of Yoshioka’s equations. Then we discuss the applications of the theory for calculating the images of high-angle phonon scattered electrons in STEM and TEM. Finally, we present a real space multislice theory which is more convenient for calculating the images and diffraction patterns of TDS electrons. The exact theory based on the real space multislice approach for simulating the composition sensitive image using diffusely scattered electrons is also outlined.
