With increasing temperature the fractals grown on a surface during submonolayer epitaxy lose their fractal character and eventually become compact islands. Experimental determination of the transition temperature is difficult and it is not known if the fractal-to-compact transition is sharp or arises gradually. In the present work, the transition is examined for the Cu/W(110) system based on kinetic...
The low-coverage growth of Cu islands deposited on W(110) is studied by kinetic Monte Carlo simulation. The model includes deposition, diffusion of monomers, diffusion along island edges and reversible aggregation on centered rectangular lattice with anisotropy of diffusion barriers. The simulations are performed at temperatures from 150 to 280K with fluxes changing from 10 -7 to 10 ...
