Abstract (German)

In dieser Arbeit wurden Ratscheneffekte betrachtet, die sich als Photoströme durch Anregung einer asymmetrisch-periodischen Struktur auf Graphen mit Ferninfrarot-Strahlung äußern. Es wird erläutert, wie verschiedene Ratschensysteme auf Basis von exfoliertem sowie epitaktisch gewachsenem Graphen realisiert wurden. Die Eigenschaften dieses Ratscheneffekts wurden experimentell bezüglich ...

Translation of the abstract (English)

In this work ratchet effects, which occur as photocurrents excited by the illumination of an asymmetric periodic pattern on graphene with FIR radiation, are discussed. It is shown how different ratchet systems were realized based on exfoliated or epitaxially grown graphene. The properties of the ratchet effect were investigated regarding polarization, angle of incidence and wavelength of the ...
