Diffuse LEED intensities of disordered crystal surfaces : IV. Application of the disorder theory.
In: Surface Science, Vol. 77, No. 2: pp. 283-300
The principles of the statistical disorder theory are discussed briefly. The theory is applied to a model of the disordered (101)Au surface with the characteristic (1 × 2) supersstructure. A fit procedure is described, by which the experimental angular intensity profiles are used directly to determine the disorder parameters and the interaction energies between the chains of surface atoms.
