Reversibility in particle deposition: The effect of mobile fraction of particles on monolayer structures
چکیده انگلیسی

In this work, the degree of reversibility in particle deposition was introduced by surface diffusion. The effect of mobile fraction of triangular-well particles on the surface among the immobile ones was explored by varying number of particles added at a time in modified sequential quenching model. It was found that at low temperatures, as the number of added mobile particles increased, the structures was composed of more compact clusters connecting to one another, thereby, decreasing the percolating density while at high temperatures, the structures are more disordered and the final structures were independent on the deposition flux, leading to the unchanged percolating density.

The fraction of mobile particles among the immobile ones, ranging from dρ∗=0.0025dρ∗=0.0025 to 0.1000 was observed to affect the monolayer structures and corresponding percolating densities at low temperatures.Figure optionsDownload as PowerPoint slide
