SURFACE SELECTIVE DECONSTRUCTION - A MONTE-CARLO STUDY

Two toy models for surface and interface disaggregation are introduced and some considerations on their relevance for real physico-chemical processes are presented. The models are studied by means of Monte Carl o simulations in 1 + 1 dimensions and the scaling laws of the interfac e width w(L, t) are determined. In both cases, the scaling is in agree ment with that obtained from the fourth order linear Langevin equation s. The result is discussed in relation to another microscopic disaggre gation model and to the microscopic growth model of Wolf and Villain.
