摘要：
This work presents a new tunable plasmonic platform on which the metamaterial resonance is coupled with infrared vibrational bond in the presence of graphene electrostatic modulation. The graphene electrostatic modulation based on the parallel-plate capacitor configuration enables the wavelength shift of 1.57 nm/V, resonance intensity and Q-factor modulation depth of 103.34% and 70% respectively. Metamaterial based plasmon polariton perfectly matched with phonon mode yields the highest Q-factor. However, this perfectly-matched resonance appears to be prohibitively "switched off" in the electrostatic tuning, which is reported for the first time.
