Large arrays of Graphene resonators developed in Cornell

Researchers from Cornell have developed large arrays of nanoscale resonators using Graphene. Each resonator is made of a film of graphene that oscillates back and forth in response to a mechanical force applied to its surface or to an electrical field.

The Cornell group first etched trenches into the surface of a silicon wafer. They then topped the wafer with a film of graphene grown on top of copper. The graphene sticks to the surface of the silicon wafer like plastic cling wrap would. The researchers finally add electrical contacts to the graphene to complete the resonators.
