EFFECT OF MONOMER EVAPORATION ON A SIMPLE-MODEL OF SUBMONOLAYER GROWTH

We present a model for thin-film growth by particle deposition that ta kes into account the possible evaporation of the particles deposited o n the surface. Our model focuses on the formation of two-dimensional s tructures, We find that the presence of evaporation can dramatically a ffect the growth kinetics of the film, and can give rise to regimes ch aracterized by different ''growth'' exponents and island size distribu tions. Our results are obtained by extensive computer simulations as w ell as through a simple scaling approach, and the analysis of rate equ ations describing the system. We carefully discuss the relationship of our model with previous studies of the same physical situation, and w e show that our analysis is more general.
