Observation of Electronic Raman Scattering in Metallic Carbon Nanotubes
Hootan Farhat, Stéphane berciaud, Martin Kalbac +4
We present experimental measurements of the electronic contribution to the Raman spectra of individual metallic single-walled carbon nanotubes (MSWNTs). Photoexcited carriers are i…
Nonlinear THz Conductivity Dynamics in CVD-Grown Graphene
Harold Y. Hwang, Nathaniel C. Brandt, Hootan Farhat +3
We report strong THz-induced transparency in CVD-grown graphene where 92%-96% of the peak-field is transmitted compared to 74% at lower field strength. Time-resolved THz-pump/THz-p…
Kohn Anomaly in Raman Spectroscopy of Single Wall Carbon Nanotubes
K. Sasaki, H. Farhat, R. Saito +1
Phonon softening phenomena of the point optical modes including the longitudinal optical mode, transverse optical mode and radial breathing mode in "metallic" single wall carbo…
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…
