Cratering Induced by Slow Highly Charged Ions on Ultrathin PMMA Films

Autor: Raquel S. Thomaz, Philipp Ernst, Pedro L. Grande, Marika Schleberger, Ricardo M. Papaléo

Publikováno v: Atoms, Vol 10, Iss 4, p 96 (2022)

Highly charged ions are a well-known tool for the nanostructuring of surfaces. We report on the thickness dependence of nanostructures produced by single 260 keV Xe38+ ions on ultrathin poly(methyl methacrylate) (PMMA) films (1 nm to 60 nm) deposited
