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…
Shaping terahertz waves using anisotropic shear modes in a van der Waals mineral
Nicolas M. Kawahala, Daniel A. Matos, Raphaela de Oliveira +4
Naturally occurring van der Waals (vdW) materials are currently attracting significant interest due to their potential as low-cost sources of two-dimensional materials. Valuable in…
The Emergence of Mem-Emitters
Victor Lopez-Richard, Igor Ricardo Filgueira e Silva, Alessandra Ames +5
The advent of memristors and resistive switching has transformed solid state physics, enabling advanced applications such as neuromorphic computing. Inspired by these developments,…
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…
Distinctive g-factor of moire-confined excitons in van der Waals heterostructures
Y. Galvão Gobato, C. Serati de Brito, Andrey Chaves +7
We investigated experimentally the valley Zeeman splitting of excitonic peaks in the photoluminescence (PL) spectra of high-quality hBN/WS2/MoSe2/hBN heterostructures at near-zero…
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…
