Ultrafast Generation of Fundamental and Multiple-order Phonon Excitations in Highly-Enriched (6,5) Single-Wall Carbon Nanotubes
Y. -S. Lim, A. R. T. Nugraha, S. -J. Cho +14
Using a macroscopic ensemble of highly-enriched (6,5) single-wall carbon nanotubes, combined with high signal-to-noise ratio, time-dependent differential transmission spectroscopy,…
Fano resonance in Raman scattering of graphene
Duhee Yoon, Dongchan Jeong, Hu-Jong Lee +4
Fano resonances and their strong doping dependence are observed in Raman scattering of single-layer graphene (SLG). As the Fermi level is varied by a back-gate bias, the Raman G ba…
Excitonic effects on coherent phonon dynamics in single wall carbon nanotubes
Ahmad R. T. Nugraha, Eric Rosenthal, Eddwi H. Hasdeo +4
We discuss how excitons can affect the generation of coherent radial breathing modes in ultrafast spectroscopy of single wall carbon nanotubes. Photoexcited excitons can be localiz…
Origin of electronic Raman scattering and the Fano resonance in metallic carbon nanotubes
Eddwi H. Hasdeo, Ahmad R. T. Nugraha, Kentaro Sato +2
Fano resonance spectra for the G band in metallic carbon nanotubes are calculated as a function of laser excitation energy in which the origin of the resonance is given by an inter…
