Researchers at Umeå University, together with researchers at Uppsala University and Stockholm University, show in a new study how nitrogen doped graphene can be rolled into perfect Archimedean nano scrolls by adhering magnetic iron oxide nanoparticles on the surface of the graphene sheets.
«Interestingly we observed that when the graphene is decorated by maghemite, the graphene sheets spontaneously start to roll into perfect Archimedean nano scrolls, while when decorated by the less magnetic hematite nanoparticles the graphene remain as open sheets, says Thomas Wågberg, Senior lecturer at the Department of Physics at Umeå University.
When the sharp tip of the STM is poised over a sheet of graphene, it produces a circular barrier on the sheet that «acts as a perfect curved mirror» for electrons, Levitov says, reflecting them along the curved surface until they begin to interfere with themselves.
