Pump-induced terahertz anisotropy in bilayer graphene
Angelika Seidl, Roozbeh Anvari, Marc M. Dignam +5
We investigate the intraband nonlinear dynamics in doped bilayer graphene in the presence of strong, linearly-polarized, in-plane terahertz fields. We perform degenerate pump-probe…
Nonlinear Charge Transport in InGaAs Nanowires at Terahertz Frequencies
Rakesh Rana, Leila Balaghi, Ivan Fotev +4
We probe the electron transport properties in the shell of GaAs/In0.2Ga0.8As core/shell nanowires at high electric fields using optical pump / THz probe spectroscopy with broadband…
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…
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…
Anisotropy of excitation and relaxation of photogenerated Dirac electrons in graphene
Martin Mittendorff, Torben Winzer, Ermin Malic +6
We investigate the polarization dependence of the carrier excitation and relaxation in epitaxial multilayer graphene. Degenerate pump-probe experiments with a temporal resolution o…
Observation of Coulomb-Assisted Dipole-Forbidden Intraexciton Transitions in Semiconductors
W. D. Rice, J. Kono, S. Zybell +14
We use terahertz pulses to induce resonant transitions between the eigenstates of optically generated exciton populations in a high-quality semiconductor quantum-well sample. Monit…
