Coherent Lattice Vibrations in Carbon Nanotubes
Y. S. Lim, K. J. Yee, J. H. Kim +6
We have generated and detected the radial-breathing mode of coherent lattice vibrations in single-walled carbon nanotubes using ultrashort laser pulses. Because the band gap is a f…
Excitons in Carbon Nanotubes with Broken Time-Reversal Symmetry
S. Zaric, G. N. Ostojic, J. Shaver +10
Near-infrared magneto-optical spectroscopy of single-walled carbon nanotubes reveals two absorption peaks with an equal strength at high magnetic fields ( 55 T). We show that th…
Ultrafast Optical Spectroscopy of Micelle-Suspended Single-Walled Carbon Nanotubes
J. Kono, G. N. Ostojic, S. Zaric +5
We present results of wavelength-dependent ultrafast pump-probe experiments on micelle-suspended single-walled carbon nanotubes. The linear absorption and photoluminescence spectra…
Luttinger Liquid Behavior in Carbon Nanotubes
M. Bockrath, D. H. Cobden, J. Lu +4
An interacting one-dimensional (1D) electron system is predicted to behave very differently than its higher-dimensional counterparts. Coulomb interactions strongly modify the prope…
Spin splitting and even-odd effects in carbon nanotubes
David H. Cobden, Marc Bockrath, Paul L. McEuen +2
The level spectrum of a single-walled carbon nanotube rope, studied by transport spectroscopy, shows Zeeman splitting in a magnetic field parallel to the tube axis. The pattern of…
Transport Spectroscopy of Single-Walled Carbon Nanotubes
David H. Cobden, Marc Bockrath, Nasreen Chopra +5
We have performed transport spectroscopy on individual ropes of single-walled carbon nanotubes. We find that the levels are Zeeman split in a magnetic field, with a g-factor of 2.0…
Single Electron Transport in Ropes of Carbon Nanotube
Marc Bockrath, David H. Cobden, Paul L. McEuen +4
We have measured the electrical properties of individual bundles, or "ropes" of single-walled carbon nanotubes. Below ~10 K, the low bias conductance is suppressed for voltages bel…
