Highly Efficient Cellular Acoustic Absorber of Graphene Ultrathin Drums

Atomically thin 2D graphene sheets exhibit unparalleled in‐plane stiffness and large out‐of‐plane elasticity, thereby providing strong mechanical resonance for nanomechanical devices. The exceptional resonance behavior of ultrathin graphene, which promises the fabrication of superior acoustic absorp...
