Abstract

Graphene sheets (GSs) are two-dimensional material with extremely favorable mass sensor properties. In the study, we examined the potential of nanoscale mass sensor based on simply supported double-layered graphene sheets (DLGSs) attached nanoparticles. Using the continuum elasticity theory, the influences of the attached mass and position of the nanoparticles on the frequency shifts of DLGSs are investigated in detail. The result shows that the frequency shift in DLGSs is much higher than that of the single-layered graphene sheets (SLGSs). The DLGSs based nanomechanical resonator could provide higher sensitivity than SLGSs.
