The theory of tensor LEED
Abstract
We present a method for highspeed surface structure determination by low energy electron diffraction called tensor LEED. Tensor LEED is a perturbative approach to the calculation of LEED I  V spectra in which an initial reference surface is distorted to generate a particular trial structure. If these atomic displacements are small then we can use a first order perturbation theory to calculate the resultant changes in the LEED I  V spectra. This leads to a highly efficient calculational technique which can reduce the computational effort expended upon a typical structure determination by several orders of magnitude.
