Ballistic deposition with sticky and non-sticky particles

Abstract

Simple (1 + 1)- and (2 + 1)-dimensional models based on the independent column model for the deposition of mixtures of sticky and non-sticky (sliding) particles have been investigated. The dependence of the surface width or perpendicular correlation length (ξ) on the time ( t) and fraction of sliding particles can be represented by the scaling form ξ(t, z) = t 2−2ƒ(tz 1) . The exponent λ has a value of 2 for models in which the deposited particles may stick only while they are being deposited and a value of 4 for models in which the particles remain sticky after they have been incorporated into the growing deposit.
