▎ 摘　　要

We investigate the dynamics behaviors of single-layered graphene sheet resonator at constant temperature via classical molecular dynamics simulations. The simulation results show that the graphene sheet resonator works in a mixed behavior, partly chaotic and partly regular, which is due to the interaction between the self-rippling of the graphene sheet and the applied gate forces. However in spite of the partial chaotic motions, the existence of regular signature can allow the development of tunable resonators. Hence the resonance frequencies as a function of the applied fate force can be regressed by the power function, this result shows the tenability of the graphene sheet resonator by controlling electrical direct current bias of the gate. Graphene resonators as ultra-sensitive sensors can be well-modeled using the tension variations induced by the applied gate force.
