▎ 摘　　要

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 Waa Is 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. So this phenomenon greatly affected the oscillatory behaviors of the graphene-nanoflake. The resonance frequencies were dependent on the initial velocity of the graphene-nanoflake. The graphene-nanoflake on the graphene-nanoribbon is applicable to ultra-fast response oscillators, data storage media, switches, sensors, and quantum computing.
