Abstract

We report electron-beam activated motion of a catalytic nanoparticle along a\ngraphene step edge and associated etching of the edge. This approach enables\nbeam-controlled etching of matter through activated electrocatalytic processes.\nThe applications of electron-beam control as a paradigm for molecular-scale\nrobotics are discussed.\n
