effect on the dynamic behavior of graphene resonators and their applications in atomic mass detection using a continuum elastic model such as modified plate theory. In particular, we developed a model based on von Karman plate theory with including the edgestress, which arises from the imbalance between
the coordination numbers of bulk atoms and edge atoms of graphene. It is shown that as the size of a graphene resonator decreases, the edgestress depending on the edge structure of a graphene resonator plays a critical role on both its dynamic and sensing performances. We found that the resonance
behavior of graphene can be tuned not only through edgestress but also through nonlinear vibration, and that the detection sensitivity of a graphene resonator can be controlled by using the edgestress. Our study sheds light on the important role of the finite-size effect in the effective design of
