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…

Ab initio calculations of edge-functionalized armchair graphene nanoribbons: Structural, electronic, and vibrational effects

Nils Rosenkranz, Christian Till, Christian Thomsen +1

We present a theoretical study on narrow armchair graphene nanoribbons (AGNRs) with hydroxyl functionalized edges. Although this kind of passivation strongly affects the structure…

Index assignment of a carbon nanotube rope using tip-enhanced Raman spectroscopy

Karin Goß, Niculina Peica, Christian Thomsen +3

We used tip-enhanced Raman spectroscopy to study the diameter-dependent Raman modes in a contacted carbon nanotube rope. We show that with the near-field tip enhancement a large nu…

Raman 2D-Band Splitting in Graphene: Theory and Experiment

Otakar Frank, Marcel Mohr, Janina Maultzsch +9

We present a systematic experimental and theoretical study of the two-phonon (2D) Raman scattering in graphene under uniaxial tension. The external perturbation unveils that the 2D…

Splitting of the Raman band of graphene subjected to strain

Marcel Mohr, Janina Maultzsch, Christian Thomsen

The Raman -band -important for the analysis of graphene- shows a splitting for uniaxial strain. The splitting depends on the strength and direction of the applied strain and on…

The two-dimensional Brillouin zone of uniaxially strained graphene

Marcel Mohr, Konstantinos Papagelis, Janina Maultzsch +1

We present an in-depth analysis of the electronic and vibrational band structure of uniaxially strained graphene by ab-initio calculations. Depending on the direction and amount of…
