Formation of nanocolumns in a metal-Teflon nanocomposite: Experiments and Kinetic Monte Carlo simulations — Lasse Rosenthal1, •Michael Bonitz1, Franz Faupel2, and Thomas Strunskus2 — 1Institut für Theoretische Physik und Astrophysik, CAU-Kiel — 2Institut für Materialwissenschaft, CAU-Kiel
One-dimensional nanoscale objects are predicted to have growing potential for many possible future nanoscale applications including electrical, optical and magnetic devices [1]. Of particular interest are ferromagnetic arrays [2] containing parallel monodispersed metallic nanocolumns and their potential use for ultrahigh-density magnetic recording media. Experiments [3] have shown that fabrication of such nanocomposites can benefit from the self-organized growth of metallic nanocolumns during the vapor-phase codeposition of metal and polymer, allowing for a single-step production process of ultrahigh-density nanocolumnar structures embedded in a polymer matrix. Our aim is to present a kinetic Monte Carlo approach [4] which provides a detailed understanding of the coupled cluster processes that are crucial for the self-organized formation of metallic nanocolumns. The dependence of the metallic filling factor and different column geometries on the deposition parameters is discussed and opposed to experimental results.
