O 5: Focus Session: Ion Beam Interaction with Surfaces and 2D Materials I

Montag, 27. März 2023, 10:30–13:00, GER 38

Ion beam techniques are an important tool in surface science and nanotechnology in terms of surface composition analysis as well as tailoring of surface properties. Recent important developments took place using ultra-low energy ion implantation to introduce foreign atoms into 2D material lattices or triggering self-organization mechanisms to form large-scale ordered crystalline surface structures. This focus session brings international specialists in the connecting fields of ion physics and surface science together to discuss recent progress to our fundamental understanding of ion-surface interactions as well as pathways towards new applications for emerging material classes.
