Tunable quantum interference in bilayer graphene in double-resonant Raman scattering
Felix Herziger, Christoph Tyborski, Oliver Ochedowski +2
The line shape of the double-resonant Raman mode in bilayer graphene is often considered to be characteristic for a certain laser excitation energy. Here, in a joint experimen…
Splitting of the monolayer out-of-plane A'1 Raman mode in few-layer WS2
Matthias Staiger, Roland Gillen, Nils Scheuschner +5
We present Raman measurements of mono- and few-layer WS2. We study the monolayer A'1 mode around 420 cm(-1) and its evolution with the number of layers. We show that with increasin…
Double-resonant LA phonon scattering in defective graphene and carbon nanotubes
Felix Herziger, Christoph Tyborski, Oliver Ochedowski +2
We present measurements of the Raman mode in graphene and carbon nanotubes at different laser excitation energies. The Raman mode around 1050 - 1150\,cm originates fro…
Photoluminescence of freestanding single- and few-layer MoS2
Nils Scheuschner, Oliver Ochedowski, Anne-Marie Kaulitz +3
We present a photoluminescence study of freestanding and Si/SiO2 supported single- and few-layer MoS2. The single-layer exciton peak (A) is only observed in freestanding MoS2. The…
Graphene on Si(111)7x7
O. Ochedowski, G. Begall, N. Scheuschner +3
We demonstrate that it is possible to mechanically exfoliate graphene under ultra high vacuum conditions on the atomically well defined surface of single crystalline silicon. The f…
