Biexciton, single carrier, and trion generation dynamics in single-walled carbon nanotubes
Bertrand Yuma, Stéphane Berciaud, Jean Besbas +10
We present a study of free carrier photo-generation and multi-carrier bound states, such as biexcitons and trions (ionized excitons), in semiconducting single-walled carbon nanotub…
All-optical trion generation in single walled carbon nanotubes
Silvia Santos, Bertrand Yuma, Stéphane Berciaud +5
We present evidence of all optical trion generation and emission in undoped single walled carbon nanotubes (SWCNTs). Luminescence spectra, recorded on individual SWCNTs over a larg…
Alignment Dynamics of Single-Walled Carbon Nanotubes in Pulsed Ultrahigh Magnetic Fields
J. Shaver, A. N. G. Parra-Vasquez, S. Hansel +6
We have measured the dynamic alignment properties of single-walled carbon nanotube (SWNT) suspensions in pulsed high magnetic fields through linear dichroism spectroscopy. Millisec…
Magneto-spectroscopy of Highly-Aligned Carbon Nanotubes: Identifying the Role of Threading Magnetic Flux
J. Shaver, S. A. Crooker, J. A. Fagan +6
We have investigated excitons in highly-aligned single-walled carbon nanotubes (SWCNTs) through optical spectroscopy at low temperature (1.5 K) and high magnetic fields ($\textbf{\…
Magnetic Brightening of Carbon Nanotube Photoluminescence through Symmetry Breaking
J. Shaver, J. Kono, O. Portugall +5
Often a modification of microscopic symmetry in a system can result in a dramatic change in its macroscopic properties. Here we report that symmetry breaking by a tube-threading ma…
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…
