Figure 5From: Nonlinear vibration behavior of graphene resonators and their applications in sensitive mass detectionEffects of pre-strain on bare graphene resonator. (a) Frequency shifts of a bare graphene resonator (i.e. without any mass adsorption) due to in-plane tension as a function of an in-plane tension N0 and actuation amplitude p0. (b) Dimensionless parameter θ of graphene resonators as a function of actuation amplitude p0 and in-plane tension N0. (c) Critical in-plane tensions, which induce the transition from nonlinear vibration to harmonic oscillation for graphene resonators, are computationally obtained as a function of the size of a graphene resonator and actuation amplitude.Back to article page
