Localized plasmonic field enhancement in shaped graphene nanoribbons
Optics Express, 2016 Graphene nanoribbon (GNR), as a fundamental component to support the surface plasmon waves, are envisioned to play an important role in graphene plasmonics. However, to achieve extremely confinement of the graphene surface plasmons (GSPs) is still a challenging. Here, we propose a scheme to realize the excitation of localized surface plasmons with very

Revealing local structural properties of an atomically thin MoSe2 surface using optical microscopy
Beilstein Journal of Nanotechnology, 2022 Using a triangular molybdenum diselenide (MoSe2) flake as surface-enhanced Raman spectroscopy (SERS) platform, we demonstrate the dependency of the Raman enhancement on laser beam polarization and local structure using copper phthalocyanine (CuPc) as ...

Plasmon localization and field enhancement in flexible metasurfaces
Physical Review AppliedWe explore the optical properties of plasmon localization and local field enhancement in metalplastic metasurface. The flexible metal-dielectric metasurface are made from modulated polycarbonate substrate coated by a thin silver film. Localization of an optical excitation is experimentally observed by near-field scanning optical microscopy within ...
