Photoluminescence dynamics in few-layer InSe
Tommaso Venanzi, Himani Arora, Stephan Winnerl +10
We study the optical properties of thin flakes of InSe encapsulated in hBN. More specifically, we investigate the photoluminescence (PL) emission and its dependence on sample thick…
Up to 70 THz bandwidth from implanted Ge photoconductive antenna excited by a fibre laser
Abhishek Singh, Alexej Pashkin, Stephan Winnerl +6
Phase-stable electromagnetic pulses in the THz frequency range offer several unique capabilities in time-resolved spectroscopy. However, the diversity of their application is limit…
Optical Control of Chiral Charge Pumping in a Topological Weyl Semimetal
M. Mehdi Jadidi, Mehdi Kargarian, Martin Mittendorff +8
Solids with topologically robust electronic states exhibit unusual electronic and optical transport properties that do not exist in other materials. A particularly interesting exam…
Carrier dynamics in graphene: ultrafast many-particle phenomena
Ermin Malic, Torben Winzer, Florian Wendler +10
Graphene is an ideal material to study fundamental Coulomb- and phonon-induced carrier scattering processes. Its remarkable gapless and linear band structure opens up new carrier r…
Slow noncollinear Coulomb scattering in the vicinity of the Dirac point in graphene
J. C. König-Otto, M. Mittendorff, T. Winzer +9
The Coulomb scattering dynamics in graphene in energetic proximity to the Dirac point is investigated by polarization resolved pump-probe spectroscopy and microscopic theory. Colli…
Symmetry-breaking supercollisions in Landau-quantized graphene
Florian Wendler, Martin Mittendorff, Jacob C. König-Otto +8
Recent pump-probe experiments performed on graphene in a perpendicular magnetic field have revealed carrier relaxation times ranging from picoseconds to nanoseconds depending on th…
