Production and mechanical characterization of graphene micro-ribbons
Maria Giovanna Pastore Carbone, Georgia Tsoukleri, Anastasios C. Manikas +3
Patterning of graphene into micro- and nano-ribbons allows for the tunability in emerging fields such as flexible electronic and optoelectronic devices, and is gaining interest for…
Stress Transfer Mechanisms at the Submicron Level for Graphene/Polymer Systems
George Anagnostopoulos, Charalampos Androulidakis, Emmanuel N. Koukaras +5
The stress transfer mechanism from a polymer substrate to a nano-inclusion, such as a graphene flake, is of extreme interest for the production of effective nanocomposites. Previou…
Experimentally derived axial stress- strain relations for two-dimensional materials such as monolayer graphene
Ch. Androulidakis, G. Tsoukleri, N. Koutroumanis +5
A methodology is presented here for deriving true experimental axial stress-strain curves in both tension and compression for monolayer graphene through the shift of the 2D Raman p…
Failure Processes in Embedded Monolayer Graphene under Axial Compression
Charalampos Androulidakis, Emmanuel N. Koukaras, Otakar Frank +7
Exfoliated monolayer graphene flakes were embedded in a polymer matrix and loaded under axial compression. By monitoring the shifts of the 2D Raman phonons of rectangular flakes of…
Phonon and structural changes in deformed Bernal stacked bilayer graphene
Otakar Frank, Milan Bousa, Ibtsam Riaz +7
We present the first Raman spectroscopic study of Bernal bilayer graphene flakes under uniaxial tension. Apart from a purely mechanical behavior in flake regions where both layers…
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…
