- Abstract
- We investigated a both-side clamped graphene-ribbon resonator by using classical molecular dynamics simulation. Dynamic features of the graphene-resonator were analyzed by the variations of its center displacement, its edge tension, the kinetic energy, and its center velocity. Especially the trace of the tension variation gave very important information to get the dynamic feature of the graphene resonator. Even though the vibration of the displacement was slightly asymmetrical due to its harmonic motions, the graphene resonator worked in stable. The effective spring constant of the graphene resonator in this work was in good agreement with the previous experiments. Such ultra-high frequency graphene resonators will facilitate the development of fast scanning probe microscopes, resonant force microscopes, mechanical supercomputers, ultrahigh frequency tuners, and nanodevices for high-frequency signal processing and biological imaging.
