▎ 摘  要

The vibrational properties of a graphene-nanoribbon-resonator were investigated by classical molecular dynamics modeling and simulations. The resonance frequency could be tuned by the induced tension due to the driving force, and increased with increasing driving force. This relation was then able to be regressed as a power function. The growth rates of the resonance frequencies exponentially decreased with increasing driving force. The resonance frequencies as a function of tension could be understood in terms of classical continuum mechanics because most of the graphene deflections were in the elastic region of the graphene strain. The modeling technique used can be applied to understand other graphene-based nanoelectromechanical devices (C) 2012 Elsevier B.V. All right's reserved.
