Tunable terahertz resonator based on intercalation doped-multilayer graphene ribbon (ID-MGR)

Graphene has been proved to be a promising candidate nanomaterial for tunable electronics. In this paper, a novel tunable terahertz resonator is proposed based on an electrically biased intercalation doped-multilayer graphene ribbon (ID-MGR). The induced self-heating effect is taken into account. Then, the equivalent circuit parameters are predicted. The resonant frequencies and Q-factors of the resonator are calculated with the equivalent single conductor (ESC) model. By properly selecting the geometry of the ID-MGR resonator and applying a biasing voltage of 1.0 V, a tuning ratio up to 21.2% can be achieved with the unloaded Q-factor around 25 for the resonant frequency around 1 THz.
