Polaritons, originating from the interactions between photons and material excitations, have
attracted attention because of their strong field compression and deeply subdiffractional …

Low-dimensional van der Waals (vdW) materials can harness tightly confined polaritonic
waves to deliver unique advantages for nanophotonic biosensing. The reduced …

The electronic structure of quasi-one-dimensional graphene nanoribbons (GNRs) is closely
related to their width, boundary configuration and heteroatomic do** because of the …

Thin layers of in-plane anisotropic materials can support ultraconfined polaritons, whose
wavelengths depend on the propagation direction. Such polaritons hold potential for the …

Abstract 2D monolayers supporting a wide variety of highly confined plasmons, phonon
polaritons, and exciton polaritons can be vertically stacked in van der Waals …

Quasi-one-dimensional graphene nanoribbons (GNRs) have atomically accurate tunability
of the electronic properties. Because of the difference in length, width, boundary type and …

We designed a perovskite nanowire-based graphene plasmonic waveguide, where the
perovskite nanowire is located on the graphene-insulator-metal (GIM) platform. The finite …

Near-field map** has been widely used to study hyperbolic phonon-polaritons in van der
Waals crystals. However, an accurate measurement of the polaritonic loss remains …

While infrared spectroscopy is a powerful technique that provides molecular information
such as chemical constituents and chemical structures of analytes, it suffers from low …

Orthorhombic molybdenum trioxide (α‐MoO3), a newly discovered polaritonic van der Waals
