Hamburg Photon Science Colloquium: ULTRAFAST ELECTRON KINETICS IN GRAPHENE

by Andreas Knorr (Technische Universität Berlin)

Friday 17 Jun 2016, 14:00 → 15:00 Europe/Berlin

CFEL, Bldg. 99 (DESY Hamburg)

Graphene is an ideal material to study new processes in the ultrafast carrier kinetics of a two-dimensional system: Its linear energy dispersion and the vanishing bandgap allow new and surprising electron scattering processes, suppressed in conventional semiconductors: A typical, fascinating example is a process which generates two optically excited electrons out of one photon.
