Force sensing with a graphene nanomechanical resonator coupled to photonic crystal guided resonances
Heng Lu, Tingting Li, Hui Hu +5
Achieving optimal force sensitivity with nanomechanical resonators requires the ability to resolve their thermal vibrations. In two-dimensional resonators, this can be done by meas…
Hysteretic responses of nanomechanical resonators based on crumpled few-layer graphene
Heng Lu, Chen Yang, Ce Zhang +8
Manipulating two-dimensional materials occasionally results in crumpled membranes. Their complicated morphologies feature an abundance of folds, creases and wrinkles that make each…
A few-layer graphene nanomechanical resonator driven by digitally modulated video signals
Ce Zhang, Heng Lu, Chen Yang +4
Nanomechanical resonators driven by multifrequency signals combine the physics of mesoscopic vibrations and the technologies of radio communication. Their simplest property stems f…
Symmetry breaking of large-amplitude parametric oscillations in few-layer graphene nanomechanical resonators
Chen Yang, YuBin Zhang, Heng Lu +6
Graphene nanomechanical resonators are well suited for the study of parametric oscillations. Their large frequency tunability and their pronounced nonlinearities enable an efficien…
