Modelling and simulation of nanoparticle formation and deposition
Modelling of various plasma-based processes, partially illustrated in the figure 1, was carried out in close cooperation with the group of Michael Bonitz from theoretical physics in Kiel. Simulations include the following subjects:
- Kinetic Monte-Carlo simulations on the formation of metallic nanoparticles and particulate nanocomposites during deposition,
- Kinetic Monte-Carlo simulations on the formation of rod-like nanostructures,
- Molecular dynamics simulations on particle coalescence in the gas phase,
- Molecular dynamics simulations on the formation of granular nanostructures upon metal sputtering on polymers.
