Abstract

We investigate a model for epitaxial film growth by particle deposition that takes into account the diffusion, aggregation and possible evaporation of the particles deposited on the surface. We find that particle evaporation can dramatically affect the growth velocity of the film, as it is experimentally observed for (0 0 1) CdTe. Puzzling features of these experiments are given a simple explanation. A model for CdTe growth is presented, and quantitative agreement is found with experimental data. Our results are obtained by extensive computer simulations as well as through a simple analytic scaling approach.
