Intercalation of atoms, ions and molecules is a powerful tool for altering or tuning the
properties—interlayer interactions, in-plane bonding configurations, Fermi-level energies …

Abstract 2D metal oxides have aroused increasing attention in the field of electronics and
optoelectronics due to their intriguing physical properties. In this review, an overview of …

Polaritons are a hybrid class of quasiparticles originating from the strong and resonant
coupling between light and matter excitations. Recent years have witnessed a surge of …

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

Anisotropic planar polaritons-hybrid electromagnetic modes mediated by phonons,
plasmons, or excitons-in biaxial two-dimensional (2D) van der Waals crystals have attracted …

Control over charge carrier density provides an efficient way to trigger phase transitions and
modulate the optoelectronic properties of materials. This approach can also be used to …

Rechargeable proton batteries are attractive, because protons as a charge carrier have a
small ionic radius, a lightest mass, and a high abundance on Earth. MoO3, as one of the …

Photonic crystals (PhCs) are a kind of artificial structures that can mold the flow of light at
will. Polaritonic crystals (PoCs) made from polaritonic media offer a promising route to …

Surface phonon polaritons (SPhPs) in polar dielectrics offer new opportunities for infrared
nanophotonics. However, bulk SPhPs inherently propagate isotropically with limited photon …

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