Effect of Evaporation on the Growth Kinetics in a Model for Two Species

A surface growth model for two species is proposed, when deposition,
surface diffusion and evaporation are considered, in (1+1)-dimensions. A
Monte-Carlo simulation is carried out, focusing on the effect of evaporation on
the evolution of the amount of roughness. The results show that the interplay
between deposition, surface diffusion and evaporation slows down the rate of
growth of the surface width. In addition, when the rate of evaporation
increases, the surface width grows faster to a higher value, in comparison to the
case of low rate of evaporation. This introduces changes in the scaling
exponents which show that evaporation should be given equal or as much
consideration as deposition and surface relaxation.
