Quasi-homogeneous surface approach

Experimental results on the basis of a kinetic approach of Me UPD on quasi-homogeneous substrate surfaces using large and small signal system perturbation techniques are rather rare [3.89, 3.119, 3.214-3.216, 3.313, 3.314]. 

These controversial results on the kinetics of Me UPD processes, obtained on the basis of the simplest approach assuming quasi-homogeneous substrate surfaces, led to the development of a different kinetic model including surface inhomogeneities, gradients of Meads> and surface diffusion as discussed in the following.
