TL;DR: This work unveils the tailored plasmonic characteristics of TBLG and deepens the understanding of the intriguing nano-optical physics in novel van der Waals coupled two-dimensional materials.

TL;DR: A nanoinfrared imaging study of the localized plasmon resonance modes of graphene nanoribbons using a scattering-type scanning near-field optical microscope (s-SNOM), which indicates that the asymmetric fringes are formed due to the interplay between the localized surface plAsmon resonance (SPR) mode excited by the GNRs and the propagative surfaceplasmon polariton (SPP) mode launched by the s- SNOM tip.

TL;DR: In this paper, the transverse-electric exciton polaritons in atomically thin WSe${}_{2}$ nanoflakes were studied using a scattering-type scanning near-field optical microscope excited by an $s$-polarized laser.

TL;DR: An innovative way to tailor band-selective electromagnetic responses at the surface of a heavy fermion compound, samarium sulfide (SmS), is demonstrated, which represents a paradigm shift for nanoscale metamaterial and metasurface design.

TL;DR: A nano-plasmonic study of vdW heterostructures that were produced by depositing ordered molecular layers of pentacene on top of graphene finds that surface plasmons formed due to the collective oscillations of Dirac fermions in graphene are highly sensitive to the adjacentpentacene layers.
