Characterizing top gated bilayer graphene interaction with its environment by Raman spectroscopy
D. L. Mafra, P. Gava, L. M. Malard +6
In this work we study the behavior of the optical phonon modes in bilayer graphene devices by applying top gate voltage, using Raman scattering. We observe the splitting of the Ram…
Doping single wall carbon nanotubes with differently charged porphyrins
G. A. M. Sáfar, H. B. Ribeiro, C. Fantini +4
Photoluminescence (PL) measurements of porphyrin-doped single wall carbon nanotubes (SWNT) were studied in sodium dodecylbenzenesulfonate (NaDDBS) aqueous dispersions. The PL spect…
Probing the Electronic Structure of Bilayer Graphene by Raman Scattering
L. M. Malard, J. Nilsson, D. C. Elias +5
The electronic structure of bilayer graphene is investigated from a resonant Raman study using different laser excitation energies. The values of the parameters of the Slonczewski-…
Direct Experimental Evidence of Exciton-Phonon Bound States in Carbon Nanotubes
Flavio Plentz, Henrique B. Ribeiro, Ado Jorio +2
We present direct experimental observation of exciton-phonon bound states in the photoluminescence excitation spectra of isolated single walled carbon nanotubes in aqueous suspensi…
