Ion Impacts on Graphene/Ir(111): Interface Channeling, Vacancy Funnels, and a Nanomesh
By combining ion beam experiments
and atomistic simulations we
study the production of defects in graphene on Ir(111) under grazing
incidence of low energy Xe ions. We demonstrate that the ions are
channeled in between graphene and the substrate, giving rise to chains
of vacancy clusters with their edges bending down toward the substrate.
These clusters self-organize to a graphene nanomesh via thermally
activated diffusion as their formation energy varies within the graphene
moiré supercell
