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…

Hot electron dynamics in a semiconductor nanowire under intense THz excitation
Andrei Luferau, Maximilian Obst, Stephan Winnerl +8
We report THz-pump / mid-infrared probe near-field studies on Si-doped GaAs-InGaAs core-shell nanowires utilizing THz radiation from the free-electron laser FELBE. Upon THz excitat…
