Mode Conversion of Hyperbolic Phonon Polaritons in van der Waals terraces
Byung-Il Noh, Sina Jafari Ghalekohneh, Mingyuan Chen +7
Electromagnetic hyperbolicity has driven key functionalities in nanophotonics, including super-resolution imaging, efficient energy control, and extreme light manipulation. Central…
Temperature-dependent Optical and Polaritonic Properties of hBN-encapsulated Monolayer TMDs
Matan Meshulam, Anabel Atash Kahlon, Yonatan Gershuni +3
Monolayer transition metal dichalcogenides (TMDs) support robust excitons in the visible to near-infrared spectral range. Their reduced dielectric screening results in large bindin…
Growth of hexagonal BN crystals by traveling-solvent floating zone
Eli Zoghlin, Juliette Plo, Gaihua Ye +11
Large, high-purity single-crystals of hexagonal BN (h-BN) are essential for exploiting its many desirable and interesting properties. Here, we demonstrate via X-ray tomography, X-r…
Exciton self-trapping in twisted hexagonal boron nitride homostructures
Sébastien Roux, Christophe Arnold, Etienne Carré +17
One of the main interests of 2D materials is their ability to be assembled with many degrees of freedom for tuning and manipulating excitonic properties. There is a need to underst…
Electroluminescence and Energy Transfer Mediated by Hyperbolic Polaritons
L. Abou-Hamdan, A. Schmitt, R. Bretel +26
Under high electrical current, some materials can emit electromagnetic radiation beyond incandescence. This phenomenon, referred to as electroluminescence, leads to the efficient e…
