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…
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…
