Long-lived Anisotropy of Photoexcited Graphene Electrons

Winnerl, S.; König-Otto, J. C.; Mittendorff, M.; Winzer, T.; Malic, E.; Knorr, A.; Pashkin, A.; Schneider, H.; Helm, M.

In polarization resolved pump-probe experiments complemented by microscopic modeling we show that an anisotropic carrier distribution persists on ps timescales. In particular, we evaluate the role of non-collinear Coulomb scattering.

Keywords: Carrier dynamics; graphene; ultrafast spectroscopy; Coulomb scattering
