Schematics and Energetics of Bucky Shuttle Memory on Graphene Nanoribbon Array.

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.

Data Archive Based on Graphene Nanoflake Shuttle Encapsulated in Bi-Layered Graphene Nanoribbon.

We present advanced schematics of graphene-nanoflake (GNF) shuttle-memory using the GNF encapsulated within bi-layered graphene nanoribon (GNR) like a sandwich and investigate its energetic and dynamic properties via classical molecular dynamics simulations. This work explicitly demonstrates that GNF shuttle encapsulated in bi-layered GNR is applicable to nonvolatile memory. Its energetics and the dynamic properties obtained from atomic-scale calculations clearly showed that this GNF shuttle encapsulated in bi-layered GNR had bi-stable minima energy position in the vdW potential energy plot.

Oscillatory Behavior of Graphene Nanoflake on Graphene Nanoribbon.

We investigated the oscillatory behaviors of graphene-nanoflake on graphene-nanoribbon via classical molecular dynamics simulations. Since the potential well had constant depth along the length axis of the graphene-nanoribbon, such as a ditch, and the retraction van der Waals forces at both edges were exerted, the movable graphene-nanoflake could be shuttled between both sides of the graphene-nanoribbon, along the direction of the ditch in the potential well. When the graphene-nanoflake was extruded from the graphene-nanoribbon, the telescoping region of the graphene-nanoflake was bent by the attractive force between the graphene-nanoribbon and the graphene-nanoflake, and this bending caused the flapping or wagging motions of the graphene-nanoflake, which dissipated the kinetic energy of the graphene-nanoflake.

Molecular dynamics simulation of square graphene-nanoflake oscillator on graphene nanoribbon.

Graphene nanoflakes (GNFs) have been of interest for a building block in order to develop electromechanical devices on a nanometer scale. Here, we present the oscillation motions of a square GNF oscillator on graphene nanoribbon (GNR) in the retracting-motions by performing classical molecular dynamics simulations. The simulation results showed that the GNF oscillators can be considered as a building block for nanoelectromechanical systems such as carbon-nanotube (CNT) oscillators.
