Scalable, Simple, and Versatile Encapsulation of 2D Materials and Devices
Gabriel Natale, Uma Chirkova, Flávio Henriques Feres +16
Air-sensitive 2D materials present a fundamental challenge for device integration. Encapsulation is often required to preserve intrinsic properties, yet conventional protection str…
Magnetic permeability and zone-folded phonons in layered NiPS
André A. A. Silva, Eduardo D. Stefanato, Nicolas M. Kawahala +8
Nickel phosphorus trisulfide (NiPS) stands out as a Mott insulator exhibiting XY-type antiferromagnetic order. In this work, we investigate the electrodynamic response of singl…
Infrared light scattering and emission from epsilon near-zero hyperbolic phonon-polaritons in two-dimensional crystals
Flavio Henrique Feres, Martin Bearzatto, Adrien Debacq +24
This work presents the near-field super-scattering and the near-field thermal emission from 2D hyperbolic crystals as general optical phenomena that link near-field nanophotonics t…
Two-dimensional talc as a natural hyperbolic material
Flávio H. Feres, Francisco C. B. Maia, Shu Chen +14
This study demonstrates that two-dimensional talc, a naturally abundant mineral, supports hyperbolic phonon-polaritons (HPhPs) at mid-infrared wavelengths, thus offering a low-cost…
Terahertz Twistoptics -- engineering canalized phonon polaritons
Maximilian Obst, Tobias Nörenberg, Gonzalo Álvarez-Pérez +11
The terahertz (THz) frequency range is key to study collective excitations in many crystals and organic molecules. However, due to the large wavelength of THz radiation, the local…
Ultrabroadband nanocavity of hyperbolic phonon polaritons in 1D-like α-MoO3
Ingrid D. Barcelos, Thalita A. Canassa, Rafael A. Mayer +7
The exploitation of phonon-polaritons in nanostructured materials offers a pathway to manipulate infrared (IR) light for nanophotonic applications. Notably, hyperbolic phonons pola…
Group velocity modulation and wavelength tuning of phonon-polaritons by engineering dielectric-metallic substrates
Flávio H. Feres, Rafael A. Mayer, Ingrid D. Barcelos +2
In analogy to the observed for single plasmon-polaritons, we show that subdiffractional hyperbolic phonon-polariton (HP2) modes confined in hexagonal boron nitride (hBN) nanocrysta…
