▎ 摘　　要

We address the simple schematics of graphene-nanoflake shuttle-memory and investigate its energetic and dynamic properties. The internal dynamics of a related model system, consisting of a graphene-nanoflake on a patterned graphene nanoribbon, are investigated via classical molecular dynamics simulations. The van der Waals interactions between the graphene-nanoflake and the patterned graphene nanoribon make bistable potential energy wells in the larger surface area regions of the patterned graphene nanoribbon, and then the graphene-flake keeps its seat on one of the bistable positions, which is the place where the binary data is archived. This graphene-nanoflake shuttle can be a tunable two-level system, where transitions between the bistable positions can be induced by applying an electric field. Nanostructures composed of graphene-nanoflake on graphene-nanoribbon are applicable to ultra-fast response oscillators, switches, sensors, and quantum computing, as well as nonvolatile memory.
