Introduction,tions of modern quantum mechanics. The pioneering experiments were performed by DAVISSON and GERMER in 1925–27 . From the very start, they recognized the potential of using this scattering from the surface region to study geometric positions of surface atoms.

The Physics of LEED,ription: these parameters (mainly atomic scattering amplitudes, inner potential and inelastic electron damping), together with multiple scattering of the electrons through the crystalline lattice, complicate the understanding of the diffraction process. For example, the analogy with X-ray diffractio
