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…
Review on Infrared Nanospectroscopy of Natural 2D Phyllosilicates
Raphaela De Oliveira, Alisson R. Cadore, Raul O. Freitas +1
Phyllosilicates emerge as a promising class of large bandgap lamellar insulators. Their applications have been explored from fabrication of graphene-based devices to 2D heterostruc…
Raman and Far Infrared Synchrotron Nanospectroscopy of Layered Crystalline Talc: Vibrational Properties, Interlayer Coupling and Symmetry Crossover
Raphael Longuinhos, Alisson R. Cadore, Hans A. Bechtel +4
Talc is an insulating layered material that is stable at ambient conditions and has high-quality basal cleavage, which is a major advantage for its use in van der Waals heterostruc…
High throughput investigation of an emergent and naturally abundant 2D material: Clinochlore
Raphaela de Oliveira, Luis A. G. Guallichico, Eduardo Policarpo +10
Phyllosilicate minerals, which form a class of naturally occurring layered materials (LMs), have been recently considered as a low-cost source of two-dimensional (2D) materials. Cl…
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…
Observation of plasmon-phonon coupling in natural 2D graphene-talc heterostructures
Ingrid D. Barcelos, Alisson R. Cadore, Ananias B. Alencar +8
Two-dimensional (2D) materials occupy noteworthy place in nanophotonics providing for subwavelength light confinement and optical phenomena dissimilar to those of their bulk counte…
Observation of Diode Behavior and Gate Voltage Control of Hybrid Plasmon-Phonon Polaritons in Graphene-Hexagonal Boron Nitride Heterostructures
Francisco C. B. Maia, Brian T. O'Callahan, Alisson R. Cadore +8
Light-matter interaction in two-dimension photonic materials allows for confinement and control of free-space radiation on sub-wavelength scales. Most notably, the van der Waals he…
Strain field of InAs QDs on GaAs (001) substrate surface: characterization by synchrotron X-ray Renninger scanning
S. L. Morelhão, L. H. Avanci, R. Freitas +1
Precise lattice parameter measurements in single crystals are achievable, in principle, by X-ray multiple diffraction (MD) experiments. Tiny sample misalignments can compromise sys…
