Abstract

A novel three-dimensional model has been proposed for simulating pulsed laser ablation plume behvior and 'micron-sized particles' movement. It describes the plume expansion in vacuum or into an environmental gas. The model combined the advantages of Monte-Carlo and Finite Element methods, being able to give a detailed image of particles behavior, both from microscopic and macroscopic points of view. The particle interaction with obstacles is aimed to provide us a more comprehensive understanding of Pulsed Laser Deposition (PLD) techniques, with the final objective of obtaining droplets-free surfaces.
