Figure 3From: Nonlinear vibration behavior of graphene resonators and their applications in sensitive mass detectionResonance behavior of graphene in nonlinear oscillation. (a) Resonance curves of a graphene resonator (with its size of D = 250 nm) as a function of actuation amplitude p0. (b) Dimensionless parameter θ, which represents the degree of nonlinearity in the vibration of a graphene resonator, as a function of actuation amplitude p0.Back to article page
