A model using a distorted wave analysis coupled with considerations of registry and channeling is developed for understanding high-energy electron diffraction from surfaces in a plan-view geometry. We show that this model explains strong effects due to inelastic scattering, particularly for the 1×1 surface as a function of beam orientation with respect to the underlying bulk substrate and with respect to the effect of registry on intensities. Numerical simulations using the multislice algorithm are correlated with the model, and show additional complications due to a top-bottom effect and coupling.
