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…
Subjecting a graphene monolayer to tension and compression
Georgia Tsoukleri, John Parthenios, Konstantinos Papagelis +5
The mechanical behaviour of graphene flakes under both tension and compression is examined using a cantilever-beam arrangement. Two different sets of samples were employed involvin…
