▎ 摘　　要

Graphene is a two-dimensional material that lias attracted a lot of attention due to the excitation of surface plasmons in the mid-infrared region. In this letter, we present the emergence of Anderson localization of propagating surface plasmon in a monolayer of graphene imbedded on a silicon random grating nanostrucl ure. Several new localized graphene surface plasmon (GSP) modes with higher intensity and quality factor occur with respect to corresponding modes in the periodic substrate structure. Although tuning the resonance wavelengths belonging to Anderson localized GSPs is a difficult task due to its random nature, here we tune these wavelengths by adjusting the Fermi energy of the monolayer graphene.
