In-situ Raman study of laser-induced graphene oxidation
Felix Herziger, Rasim Mirzayev, Emanuele Poliani +1
We present in-situ Raman measurements of laser-induced oxidation in exfoliated single-layer graphene. By using high-power laser irradiation, we can selectively and in a controlled…
Understanding double-resonant Raman scattering in chiral carbon nanotubes: Diameter and energy dependence of the mode
Felix Herziger, Asmus Vierck, Jan Laudenbach +1
We present a theoretical model to describe the double-resonant scattering process in arbitrary carbon nanotubes. We use this approach to investigate the defect-induced mode in…
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…
Newly observed first-order resonant Raman modes in few-layer MoS
Nils Scheuschner, Roland Gillen, Matthias Staiger +1
We report two new first-order Raman modes in the spectra of few-layer MoS at 286~cm and 471~cm for excitation energies above 2.4~eV. These modes appear only in fe…
Beyond double-resonant Raman scattering: UV Raman spectroscopy on graphene, graphite and carbon nanotubes
Christoph Tyborski, Felix Herziger, Roland Gillen +1
We present an analysis of deep-UV Raman measurements of graphite, graphene and carbon nanotubes. For excitation energies above the strong optical absorption peak at the point i…
