Kohn Anomalies in Graphene Nanoribbons
Ken-ichi Sasaki, Masayuki Yamamoto, Shuichi Murakami +6
The quantum corrections to the energies of the point optical phonon modes (Kohn anomalies) in graphene nanoribbons are investigated. We show theoretically that the longitudinal…
Growth of large-area single- and bi-layer graphene by controlled carbon precipitation on polycrystalline Ni surfaces
Alfonso Reina, Stefan Thiele, Xiaoting Jia +4
We report graphene films composed mostly of one or two layers of graphene grown by controlled carbon precipitation on the surface of polycrystalline Ni thin films during atmospheri…
Chirality dependent frequency shift of radial breathing mode in metallic carbon nanotubes
K. Sasaki, R. Saito, G. Dresselhaus +3
A phonon frequency shift of the radial breathing mode for metallic single wall carbon nanotubes is predicted as a function of Fermi energy. Armchair nanotubes do not show any frequ…
Curvature induced optical phonon frequency shift in metallic carbon nanotubes
K. Sasaki, R. Saito, G. Dresselhaus +3
The quantum corrections to the frequencies of the point longitudinal optical (LO) and transverse optical (TO) phonon modes in carbon nanotubes are investigated theoretically. T…
Selection Rules for One- and Two-Photon Absorption by Excitons in Carbon Nanotubes
Eduardo B. Barros, Rodrigo. B. Capaz, Ado Jorio +7
Recent optical absorption/emission experiments showed that the lower energy optical transitions in carbon nanotubes are excitonic in nature, as predicted by theory. These experimen…
