The integration of functional nanomaterials and heterostructures with photonic architectures
has laid the foundation for important photonic and optoelectronic applications. The advent of …

Polaritons are hybrid excitations of matter and photons. In recent years, polaritons in van der
Waals nanomaterials—known as van der Waals polaritons—have shown great promise to …

Two-dimensional (2D) materials including graphene, transition metal dichalcogenides, black
phosphorus, MXenes, and semimetals have attracted extensive and widespread interest …

Hexagonal boron nitride (h‐BN), an insulating 2D layered material, has recently attracted
tremendous interest motivated by the extraordinary properties it shows across the fields of …

For more than seven decades, hexagonal boron nitride (hBN) has been employed as an
inert, thermally stable engineering ceramic; since 2010, it has also been used as the optimal …

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 …

In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic
phenomena and systems as they appear in the literature on quantum materials and …

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

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 …

Two dimensional hexagonal boron nitride (2D-hBN), an isomorph of graphene with a very
similar layered structure, is uniquely featured by its exotic opto-electrical properties together …
