Fluctuations and scaling in models for particle aggregation
Daniele Vilone, Claudio Castellano, Paolo Politi
We consider two sequential models of deposition and aggregation for particles. The first model (No Diffusion) simulates surface diffusion through a deterministic capture area, whil…
Breakdown of metastable step-flow growth on vicinal surfaces induced by nucleation
Daniele Vilone, Claudio Castellano, Paolo Politi
We consider the growth of a vicinal crystal surface in the presence of a step-edge barrier. For any value of the barrier strength, measured by the length l_es, nucleation of island…
Nucleation and step-edge barriers always destabilize step-flow growth of a vicinal surface
Daniele Vilone, Claudio Castellano, Paolo Politi
We consider the effect of nucleation on a one-dimensional stepped surface, finding that step-flow growth is metastable for any strength of the additional step-edge barrier. The sur…
