  • Graphene electrodes revolutionize the scaling of piezoelectric NEMS resonators

    Nanowerk - 06/16/2015

    “The key challenges associated with the development of high performance MEMS and NEMS resonators for RF wireless communication and sensing applications are the isolation of energy-dissipating mechanisms and scaling of the device volume in the nanoscale size-range,” Rinaldi, an assistant professor in the Department of Electrical and Computer Engineering at Northeastern University, tells Nanowerk. “We show that a virtually massless and strainless single-atom-thick sheet of carbon, closely mimics an ‘ideal electrode’ for piezoelectric nanoelectromechanical resonators. This allows graphene-electrode based piezoelectric NEMS resonators to operate at their theoretical ‘unloaded’ frequency-limits, with significantly improved electromechanical performance compared to metal-electrode counterparts, despite their reduced volumes.”
