Kurzfassung englisch:
Atomically thin materials probed by highly charged ions are an ideal model system to unravel charge
exchange processes inside materials: Monolayer materials like single-layer graphene or MoS2 naturally limit
the interaction time of medium-energy ions with the material to a few fs only. Nevertheless, we find in our
experiments that this short period allows for (almost) complete neutralisation. Consequently, the ion´s
potential energy - several tens of keV arising from the sum of binding energies of all missing electrons - can
be deposited within one material layer alone. Here, I will discuss the mechanism which drives the energy
transfer between ion and monolayer materials as well as their heterostructures.
