Creation and sculpting of graphene with ion and electron beams

This talk will cover our recent work on the creation of graphene by ion implantation of carbon into copper substrates followed by a prescribed annealing procedure. We also discuss nanopore nucleation with ion beams and the direct observation of nanopore growth in an aberration corrected TEM. We discuss the cross-sections and knock-on energy transfers required for edge atom removal and demonstrate the controlled growth of monodisperse nanopores in graphene with atomic precision.
