Abstract
In this letter, we have constructed a simple 1 + 1 dimension model by considering shadowing effect, bonding limitation, and monomer bulk diffusion, to simulate linear polymer thin film growth under vapor deposition polymerization. The simulation shows that the polymer chain length, the width of growth front, the film thickness, as well as the interfacial depth between the film and substrate increase as a function of the ratio of diffusion coefficient to deposition rate G, while the density of the polymer film decreases with G. These results are qualitatively consistent with some existing experimental results.
