Abstract

The stochastic Eden model of charged particles aggregation in twodimensional systems is presented This model is governed by the following two parameters screening length of electrostatic interaction γ and shortrange attraction energy E Different patterns of finite and infinite aggregates are observed They are of the following morphology types linear or linear with bending wormlike DBM densebranching morphology DBM with nucleus and compact Edenlike The transition between the different modes of growth is studied and phase diagram of the growth structures is obtained in γ E coordinates The detailed aggregate structure analysis including analysis of their scaling properties is presented The scheme of the internal inhomogeneous structure of aggregates is proposed
