The integration of dissimilar materials into heterostructures has become a powerful tool for
engineering interfaces and electronic structure. The advent of 2D materials has provided …

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 …

Terahertz radiation has become an important diagnostic tool in the development of new
technologies. However, the diffraction limit prevents terahertz radiation (λ≈ 0.01–3 mm) …

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 …

The photoexcitation life cycle from incident photon (and creation of photoexcited electron–
hole pair) to ultimate extraction of electrical current is a complex multiphysics process …

Infrared and optical spectroscopy represents one of the most informative methods in
advanced materials research. As an important branch of modern optical techniques that has …

Plasmons, collective oscillations of electron systems, can efficiently couple light and electric
current, and thus can be used to create sub-wavelength photodetectors, radiation mixers …

Abstract Electron–electron (e–e) collisions can impact transport in a variety of surprising and
sometimes counterintuitive ways,,,,,. Despite strong interest, experiments on the subject …

The ability to confine light into tiny spatial dimensions is important for applications such as
microscopy, sensing, and nanoscale lasers. Although plasmons offer an appealing avenue …
