Simulation of Nanocolumn Formation in a Plasma Environment — •Jan Willem Abraham¹, Thomas Strunskus², Franz Faupel², and Michael Bonitz¹ — ¹Institut für Theoretische Physik und Astrophysik, CAU Kiel — ²Institut für Materialwissenschaft, CAU Kiel

Recent experiments and kinetic Monte Carlo (KMC) simulations [1,2] demonstrated that physical vapor co-deposition of a metal alloy (Fe-Ni-Co) and a polymer (Teflon AF) can lead to self-organized growth of magnetic nanocolumns. While these experiments have been carried out with thermal sources, we analyze the feasibility of this process for the case of a sputtering source. For that purpose, we extend our previous simulation model by including a process that takes into account the influence of ions impinging on the substrate [3]. The simulation results predict that metal nanocolumn formation should be possible. Furthermore, we show that the effect of ions, which create trapping sites for the metal particles, is an increased number of nanocolumns.
