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…
Observation of Individual Josephson Vortices in YBCO Bicrystal Grain-boundary Junctions
H. Xin, D. E. Oates, S. Sridhar +2
The response of YBCO bicrystal grain-boundary junctions to small dc magnetic fields (0 - 10 Oe) has been probed with a low-power microwave (rf) signal of 4.4 GHz in a microwave-res…
Comparison of Power Dependence of Microwave Surface Resistance of Unpatterned and Patterned YBCO Thin Film
H. Xin, D. E. Oates, A. C. Anderson +3
The effect of the patterning process on the nonlinearity of the microwave surface resistance of YBCO thin films is investigated. With the use of a sapphire dielectric resonat…
Size Effects in Carbon Nanotubes
C. -H. Kiang, M. Endo, P. M. Ajayan +2
The inter-shell spacing of multi-walled carbon nanotubes was determined by analyzing the high resolution transmission electron microscopy images of these nanotubes. For the nanotub…
