Many-Beam Calculation of Reflection High Energy Electron Diffraction (RHEED) Intensities by the Multi-Slice Method

In order to calculate RHEED intensities by using the dynamic electron diffraction theory, crystals are sliced in thin stabs parallel to the surface. The crystal potential in each stab is taken as constant the normal to the surface. The RHEED intensities are calculated from the products of matrices obtained from Bethe's dynamic diffraction theory for each slab.
