Surface growth of two kinds of particle deposition models

The surface growth of two kinds of particles (A and C) depositing on a (1+1)-dimensional substrate has been studied. For two different models, the randomlike deposition and the ballisticlike deposition, the scaling behavior of the surface width W against the time t is obtained for different values of the deposition probability P of particle C. We found that the scaling behavior of the randomlike deposition model falls in the Edwards-Wilkinson class, while that of the ballisticlike deposition model belongs to the Kardar-Parisi-Zhang class. We also found that the saturated surface widths have a nonmonotonic relationship dependent on the probability P for both models.
