This thesis comprises an elaborate theoretical study on the nonequilibrium carrier dynamics
in graphene. Based on a density matrix formalism, a microscopic model is developed …

We consider the existence of plasmons in a nonequilibrium situation where electrons from
the valence band of graphene are pumped to states in the Brillouin zone around the M point …

Due to the raising demand on electrical energy the field of organic solar cells evolved
rapidly within the last decades. The detailed knowledge about energy transport within any …
