Abstract

The percolation behaviour during the deposit formation, when the spanning cluster was formed in the substrate plane, was studied. Two competitive or mixed models of surface layer formation were considered in (1+1)-dimensional geometry. These models are based on the combination of ballistic deposition (BD) and random deposition (RD) models or BD and Family deposition (FD) models. Numerically we find, that for pure RD, FD or BD models the mean height of the percolation deposit hˉ\bar h grows with the substrate length LL according to the generalized logarithmic law hˉ(ln(L))γ\bar h\propto (\ln (L))^\gamma, where γ=1.0\gamma=1.0 (RD), γ=0.88±0.020\gamma=0.88\pm 0.020 (FD) and γ=1.52±0.020\gamma=1.52\pm 0.020 (BD). For BD model, the scaling law between deposit density pp and its mean height hˉ\bar h at the point of percolation of type pphˉ1/νhp-p_\infty \propto \bar h^{-1/\nu_h} are observed, where νh=1.74±0.02\nu_h =1.74\pm0.02 is a scaling coefficient. For competitive models the crossover, %in hh versus LL corresponding to the RD or FD -like behaviour at small LL and the BD-like behaviour at large LL are observed.
