High frequency graphene resonators

ORAL

Abstract

We study mechanical resonance properties of suspended graphene devices through radio frequency electromechanical~downmixing techniques. Taking advantage of graphene's atomically thin nature, unusually large transconductance, and extremely high Young's Modulus, we have fabricated high-frequency suspended graphene resonators.~Our global-gate devices have resonated at over 500MHz in a low temperature environment with reasonable quality factors. This research will pave the way for high-quality resonators in the GHz regime which will be used in high frequency applications such as ultra high sensitive mass, chemical and charge detectors.
