Excitation of localized graphene plasmons by using non-periodical self-assembled arrays of metallic antennas

Graphene plasmons in the THz/midIR range are normally excited by using lithography prepared grating with elements 300-20 nm width.However mass reproduction of such gratings by lithography on macroscopic area of ∼1cm2 is labor-consuming and expensive technology. We study the generation of graphene pl...

Description
Summary:Graphene plasmons in the THz/midIR range are normally excited by using lithography prepared grating with elements 300-20 nm width.However mass reproduction of such gratings by lithography on macroscopic area of ∼1cm2 is labor-consuming and expensive technology. We study the generation of graphene plasmons generated using randomly oriented particle-like nanorods prepared by cheap self-assembling method. The THz/midIR graphne plasmons localized under metallic rods which are strongly coupled with graphene and are capable to enhance absorption of standing-by molecules.
