Ultrafast Electron Kinetics in Graphene

Hamburg Photon Science Colloquium
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 surpising electron scattering processes, suppressed in conventional semiconductors: A typical, fascinating example is a process which generates two optically excited electrons out of one photon.
