A snap shot from molecular dynamics calculations showing how an iron particle (pink) ingests carbon atoms (blue) from a graphene surface below is shown. The process results in the creation of holes in the graphene sheet and the formation of “holey graphene”. As reported by Mauricio Terrones and co-workers on page 76, the calculations explain how iron particles can catalyze the formation of holes in graphene by a low energy electron beam using an aberration-corrected high-resolution transmission electron microscope.
