Tuning the Morphology of Self‐Assembled Nanopatterns on MgO(001) Surfaces by Sequential Broad‐Beam Ion Irradiation

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
A two‐step approach based on broad‐beam ion irradiation is demonstrated to produce fine‐tuned self‐assembled surface patterns on MgO(001). It shows an efficient route to modifying the crystalline MgO(001) surface topography in a controlled way, making use of its very specific behavior in terms of both the pattern morphology and patterning dynamics.
