We propose a selective disaggregation model in three dimensions with a mixed Brownian-deterministic motion of the etchant particle driven by a tuning parameter taking into account the presence of an external field. The width of the surface sites in saturation is described by the...

In this paper, we propose a surface disaggregation model in (2+1) dimensions with biased motion of the eroding particle. The deconstruction is subject to selection criteria depending on the local coordination number of the extracted surface site. The surface width is investigated at early times...
