Kinetic Roughening in Deposition with Suppressed Screening

Abstract

Models of irreversible surface deposition of k-mers on a linear lattice, with screening suppressed by disallowing overhangs blocking large gaps, are studied by extensive Monte Carlo simulations of the temporal and size dependence of the growing interface width. Despite earlier finding that for such models the deposit density tends to increase away from the substrate, our numerical results place them clearly within the standard KPZ universality class. PACS numbers: 68.10.Jy, 82.20.Wt – 1 – The standard, KPZ [1] model of kinetic roughening of growing surfaces (reviewed, e.g., in [2-3]) yields the scaling prediction for the interfacial width W as a function of time, T, and substrate size, L, W ≃ L ζ F ( TL −z) , (1) where for 1D substrates, ζKPZ =
