title: Schematics and Energetics of Bucky Shuttle Memory on Graphene Nanoribbon Array.
abstract: Conjugated carbon nanomaterials such as fullerene-nanotube, fullerene-graphene, and nanotube-graphene hybrids have great potential for various applications. This paper presents the schematics and energetics of a nonvolatile nanomemory element based on a fullerene-nanotube-graphene hybrid. The system proposed was composed of C60 fullerene and a nanotube placed on two graphene-nanoribbons with a gap. The C60 fullerene encapsulated in the nanotube can shuttle between two graphene-nanoribbons along the nanotube under the alternatively applied force fields. When the encapsulated C60 fullerene settles on the graphene-nanoribbons, the local energy minima are achieved from the attractive van der Waals potential energies. Since the C60 fullerene retains its position on the graphene-nanoribbon without external force fields, the proposed system can then operate a nonvolatile memory device.
