A Study on Nanosensor Based on Graphene Nanoflake Transport on Graphene Nanoribbon Using Edge Vibration

The superlubricating motion of graphene nanoflakes on graphene has enabled further applications of graphene for directional molecular transfer and programmable motion. Here, we explore the possibility of harnessing the vibrational energy of graphene nanoribbons to control the motion of small graphene nanoflakes using nonequilibrium molecular dynamics simulations. Attempts to systematically investigate the graphene-graphene transport mechanism have focused on the fundamental driving mechanism of motion and the quantitative influence of important parameters such as oscillation frequency on the motion of nanoflakes. The results based on molecular dynamics simulations have demonstrated that the vibrational frequency plays an important key role in the directional motion of the nanoflake on nanoribbon .
