| Moving silicon atoms in graphene with atomic precision Posted: 12 Sep 2014 08:24 AM PDT 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. Scientists have now 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. |
