WebGraphene-enhanced optoelectronic terahertz (THz) signal processing offers an exquisite potential for tailoring extreme-subwavelength platforms to develop tunable and highly-responsive photonic tools. In this study, we propose a hybrid graphene island-mediated THz metadevice to support tunable charge transfer plasmon (CTP) resonances. WebGraphene islands grown epitaxially on 6H-SiC 0001 were studied using scanning tunneling microscopy and spectroscopy. Under specific growth conditions, 10 nm single-layer graphene islands are observed on top of the SiC buffer layer and align with the SiC 0001 -1 1 lattice directions. Atomic-resolution images show that
