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…
Symmetry properties of vibrational modes in graphene nanoribbons
Roland Gillen, Marcel Mohr, Janina Maultzsch
We present symmetry properties of the lattice vibrations of graphene nanoribbons with pure armchair (AGNR) and zigzag edges (ZGNR). In non-symmorphic nanoribbons the phonon modes a…
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…
Vibrational properties of graphene nanoribbons by first-principles calculations
Roland Gillen, Marcel Mohr, Janina Maultzsch +1
We investigated the vibrational properties of graphene nanoribbons by means of first-principles calculations on the basis of density functional theory. We confirm that the phonon m…
First-principles calculations of the vibrational properties of bulk CdSe and CdSe nanowires
M. Mohr, C. Thomsen
We present first-principles calculations on bulk CdSe and CdSe nanowires with diameters of up to 22 Å. Density functional linear combination of atomic orbitals and plane wave calcu…
