Amorphous carbon irradiated by electrons at acceleration voltages of 80 kV is studied in high‐resolution transmission electron microscopy. Amorphous carbon deposited on graphene or h‐BN membranes forms graphene layers parallel to the support due to van der Waals interactions. One can use deposited amorphous carbon to engineer graphene either for its catalyst‐free fabrication or its destruction.
