Journal ArticleDOI
Inhomogeneous optical absorption around the K point in graphite and carbon nanotubes
Alexander Grüneis,Riichiro Saito,Ge. G. Samsonidze,T. Kimura,Marcos A. Pimenta,Ado Jorio,Ado Jorio,A. G. Souza Filho,A. G. Souza Filho,G. Dresselhaus,Mildred S. Dresselhaus +10 more
TL;DR: In this paper, the optical absorption spectra of graphite and carbon nanotubes are calculated for a single-wall carbon nanophase and the chirality dependence of the absorption matrix element is analyzed analytically.
Journal ArticleDOI
Double resonance Raman spectroscopy of single-wall carbon nanotubes
Riichiro Saito,Alexander Grüneis,Ge. G. Samsonidze,Victor W. Brar,G. Dresselhaus,Mildred S. Dresselhaus,Ado Jorio,Luiz Gustavo Cançado,Cristiano Fantini,Marcos A. Pimenta,A. G. Souza Filho +10 more
TL;DR: In this article, a review of double resonance Raman spectroscopy is presented, where non-zone center phonon modes in solids can be observed in the double-resonance Raman spectrum, in which weak Raman signals appear in a wide frequency region and their combination or overtone modes can be assigned.
Journal ArticleDOI
Resonance Raman spectroscopy ( n , m ) -dependent effects in small-diameter single-wall carbon nanotubes
Ado Jorio,Cristiano Fantini,Marcos A. Pimenta,Rodrigo B. Capaz,Ge. G. Samsonidze,G. Dresselhaus,M. S. Dresselhaus,Jie Jiang,Nagao Kobayashi,Alexander Grüneis,Riichiro Saito +10 more
TL;DR: In this paper, an accurate analysis of the electronic transition energies and radial breathing mode (RBM) frequencies from 40 small-diameter single-wall carbon nanotubes (SWNTs) in the diameter range $07l{d}_{t}l13\phantom{\rule{03em}{0ex}}\mathrm{nm}$ is presented.
Journal ArticleDOI
D-band Raman intensity of graphitic materials as a function of laser energy and crystallite size
Kentaro Sato,Riichiro Saito,Yutaka Oyama,Jie Jiang,Luiz Gustavo Cançado,Marcos A. Pimenta,Ado Jorio,Ge. G. Samsonidze,G. Dresselhaus,M. S. Dresselhaus +9 more
TL;DR: In this paper, the Raman intensity of the disorder-induced D-band in graphitic materials is calculated as a function of the in-plane size of the graphite nanoparticles (La) and as a result of the excitation laser energy.
Journal ArticleDOI
Nanowires and nanotubes
M. S. Dresselhaus,Yuxuan Lin,Oded Rabin,Ado Jorio,Ado Jorio,A. G. Souza Filho,A. G. Souza Filho,Marcos A. Pimenta,Riichiro Saito,Ge. G. Samsonidze,G. Dresselhaus +10 more
TL;DR: In this paper, the structure and properties of bismuth nanowires and carbon nanotubes are discussed and compared with those of carbon nanostructures and nanoscience concepts.
