Vibrational behavior of graphene nanoribbon-based nanoresonators

Graphene, an atomically thin layer of carbon atoms tightly packed into a two-dimensional (2D) honeycomb lattice [1], has extremely high stiffness along the basal plane and it is the strongest material ever measured by experiments [2]. Relative experiments have shown that Young's modulus of graphene is about 1.0 TPa [2]. The superior mechanical properties of graphene make it ideally suited for nanoresonators, since Young's modulus is a key factor to improve the frequencies of nanoresonators [3, 4]. Here, we investigate the vibrational characteristics of graphene nanoribbon-based nanoresonators using molecular dynamics method based on Forcite module in Materials Studio.
