Abstract
Using a two-dimensional isotropic adparticle diffusion law the cross-correlation function of the field emission fluctuations is calculated. The influence of the different geometrical parameters including the distance between probe regions is investigated. The results are compared with measurements of the adsorption system W(112)K for a chosen coverage. Some conclusions are drawn referring to the experimental arrangement and the explanation of cross-correlation functions.
