• behavior of graphene can be tuned not only through edge stress but also through nonlinear vibration, and that the detection sensitivity of a graphene resonator can be controlled by using the edge stress. Our study sheds light on the important role of the finite-size effect in the effective design of

• graphene resonators for their mass sensing applications. Keywords: edge stress; graphene resonator; mass sensing; nonlinear vibration; size effect; sensitivity; Introduction Recent advances in nanotechnology have allowed for the development of nano-electro-mechanical system (NEMS) devices that can

• stress has an impact on the dynamic and sensing performances of a graphene resonator. The effect of edge stress on the nonlinear vibration of a graphene resonator has not been studied, even though the graphene resonator can easily reach the nonlinear vibration regime due to the fact that the vibration
