The direct radio frequency read out method based on local back-gate graphene resonant channel transistor (RCT) is studied by combining the operation principles of graphene field-effect transistor and mechanical resonator. A novel method of fabricating local gate graphene RCT is proposed, and a graphene RCT with 1 m 1 m dimension channel is realized based on exfoliation graphene. The measured resonant frequency of graphene RCT is in a range of 57.5-88.25 MHz at room temperature. This work is useful to pave the way of graphene application to Nano-eletromechanical system and high frequency low-noise amplifier.
