Diffraction of low-energy electrons at a rippled surface

An analysis is made of a kinematic model of the scattering of low-energy electrons at a onedimensional periodic toothed structure simulating a rippled surface. Calculations of the intensity profiles of the diffraction peaks are made for periodic systems of identical symmetrical triangular teeth with a variable number of atoms on each generatrix of the tooth and various angles of inclination of the generatrices to the horizontal. The main effect observed as a result of scattering at a periodic toothed structure involves broadening or splitting of the diffraction peaks compared with the diffraction patterns from a smooth chain of atoms.
