Kurzfassung englisch:
The unique properties of single layer graphene (SLG) can be modified by inducing defects in the honeycomb lattice, either by collisions with energetic particles or by applying external fields. We maximize the latter effect locally by investigating the electronic response of SLG to an extremely large external field, the Coulomb field of an approaching slow highly charged ion (HCI) with charge states up to q=35. Charge exchange and energy loss of the HCI after transmission through freestanding SLG are measured and extremely short charge-equilibration times are found. Additionally, the energy loss of highly charged projectiles is strongly enhanced and increases quadratically with the incident projectile charge state.
