Growth morphology for a ballistic deposition model for multiple species

The kinetics and morphology of surface growth are studied for a ballistic deposition model with two kinds of particles (A and C) in $1+1$ and $2+1$ dimensions. A morphological structural transition is found as the probability of being a particle C increases. This transition is well defined by the different behavior of the surface width when it is plotted versus time and probability. The calculated exponents {α} and {β} for different values of probability show the same behavior. We attribute this transition to the formation of wide vacancies during the growth while the interface advances.
