Fourier transforms in surface structure determination from LEED. The transform-deconvolution method

Abstract

Fourier transforms of LEED intensities contain convolution products of functions of the interatomic vectors with data truncation, lattice vibration and potential windows. The dominant structural information in the transform originates from kinematical processes. Extraction of structural parameters of the surface, can be achieved upon a proper deconvolution of the windows from the transforms of the intensities.
