Surface phenomena in RHEED and REM

Based upon previous results for the Bloch-wave solution in the Bragg case and the consistency between the Bloch-wave solution and multislicing in the Bragg case, a complete numerical solution has been developed for reflection electron diffraction called the Bloch wave and multislice combined for reflection (BMCR) method. Results are presented of applying the BMCR method to several problems in high-energy electron reflection. First, simulations of the effects of surface reconstruction and adsorption on RHEED patterns are reported. Next, the results of simulations of surface steps are shown and their effects on the wave field analyzed numerically. Last, the existence of the surface wave which is related to electron surface resonance phenomena is demonstrated. (orig.)
