摘要: We report a highly efficient tunable THz reflector in graphene. By applying small gate voltage (up to ±3 V), the reflectance of graphene is modulated from minimum 0.79% maximum 33.4% using graphene/ionic liquid structures at room temperature, and reflection tuning uniform within wide spectral range (0.1–1.5 THz). Our observation explained by Drude model, which describes wave-induced intraband transition This may contribute broadband mirrors, deformable variable beam splitters other optical components.
