Stress-enhanced chemical vapor deposited graphene NEMS RF resonators
2013 Joint European Frequency and Time Forum & International Frequency Control Symposium (EFTF/IFC)
In this work we present room-temperature measurements of graphene nanoelectromechanical resonators (GN-ERs) demonstrating quality factors (Qs) greater than 200 at resonance. A nominal resonant frequency (fo) of 200 MHz is attained by applying strain to the suspended graphene using an SU-8 polymer clamp. Additionally, the device fo can be tuned by more than 5% by application of a DC gate bias on the order of 5V. Chemical vapor deposited (CVD) graphene is used to demonstrate the scalability of the process.doi:10.1109/eftf-ifc.2013.6702216 fatcat:xklcdmp3rbfx3lgv3sv7ig7wyy
