Low-energy electron diffraction from imperfect structures
For simple kinetic scattering, the problem of diffraction from imperfect structures reduces to finding the average autocorrelation function of the structure, modulating it with an appropriate instrumental transfer function, and taking the Fourier transform.

| Summary: | For simple kinetic scattering, the problem of diffraction from imperfect structures reduces to finding the average autocorrelation function of the structure, modulating it with an appropriate instrumental transfer function, and taking the Fourier transform. Using this approach, the effect on the diffraction beam profiles of a statistical distribution of phase shift boundaries is treated for a one-dimensional analogue of the surface. Specific calculations are made for the case of continuous beam splitting observed during the transformation from a double-spaced to a triple-spaced structure. The results demonstrate the large degree of structural anarchy that can be concealed by the deficiencies of the experimental technique. |
