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.
Graphene has a multitude of striking properties that make it an exceedingly attractive material for various applications, many of which will emerge over the next decade. However, one of the most promising applications lie in exploiting its peculiar electronic properties which are governed by its electrons obeying a linear dispersion relation. This leads to the observation of half integer quantum hall...
