Moving silicon atoms in graphene with atomic precision

In recent years, it has become possible to see directly individual atoms using electron microscopy – especially in graphene, the one-atom-thick sheet of carbon. An international collaboration between the University of Vienna and research teams from the UK and the US has shown how an electron beam can move silicon atoms through the graphene lattice without causing damage. The research combines advanced electron microscopy with demanding computer simulations and is published in the premier physics journal Physical Review Letters.
