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…
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…
Microscopic description of intraband absorption in graphene: the occurrence of transient negative differential transmission
Faris Kadi, Torben Winzer, Ermin Malic +1
We present a microscopic explanation of the controversially discussed transient negative differential transmission observed in degenerate optical pump-probe measurements in graphen…
