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…
Imaging vibrations of locally gated, electromechanical few layer graphene resonators with a moving vacuum enclosure
Heng Lu, Chen Yang, Ye Tian +9
Imaging the vibrations of nanomechanical resonators means measuring their flexural mode shapes from the dependence of their frequency response on in-plane position. Applied to two-…
