Electronic Excitations and Dynamics in Carbon Nanotubes Induced by Femtosecond Pump-Probe LASER Pulses

چکیده
We have continued our efforts in the J. R. Macdonald Laboratory directed toward the study of electronic excitations and dynamics in carbon nanotubes excited by femtosecond pump-probe laser pulses generated by the ultra-fast Ti:Sapphire Kansas Light Source, KLS. We use time-of-flight of electrons emitted from carbon nanotubes to deduce the energy and temporal behavior of the electronic states of the nanotubes. Experiments have been performed on multiwalled carbon nanotubes, MWNT, and more recently on both double walled carbon nanotubes, DWNT, and single walled carbon nanotubes, SWNT. ________________________________________________ MWNT: Quasi-ballistic transport of charge carriers in multi walled carbon nanotubes.

Femtosecond laser nanosurgery of defects in carbon nanotubes.
All self-assembled nanostructures, like carbon nanotubes, exhibit structural imperfections that affect their electronic and mechanical properties and constitute a serious problem for the development of novel electronic nanodevices. Very common defects in nanotubes are pentagon-heptagon pairs, in which the replacement of four hexagons by two pentagons and two heptagons disrupts the perfect hexag...
متن کاملSub-100 fs two-color pump-probe spectroscopy of Single Wall Carbon Nanotubes with a 100 MHz Er-fiber laser system
An extremely compact and versatile near-infrared two-color femtosecond pump-probe spectroscopy apparatus based on an amplified Erfiber laser system is presented and applied to the characterization of the relaxation dynamics of single-wall carbon nanotubes with fundamental absorption in the 2 μm spectral region. By implementing a fast-scan technique, dynamics as long as 3 ps are acquired in 5 s ...
متن کاملStability of high-density one-dimensional excitons in carbon nanotubes under high laser excitation.
Through ultrafast pump-probe spectroscopy with intense pump pulses and a wide continuum probe, we show that interband exciton peaks in single-walled carbon nanotubes (SWNTs) are extremely stable under high laser excitations. Estimates of the initial densities of excitons from the excitation conditions, combined with recent theoretical calculations of exciton Bohr radii for SWNTs, suggest that t...
متن کاملSpectral modulation of femtosecond laser pulse induced by molecular alignment revivals.
We demonstrate experimentally and numerically that the quantum wake of molecular alignment induced by impulsive rotational Raman excitations with femtosecond pump pulses produces observable phase modulations on femtosecond probe pulses. This leads to a spectral red- or blueshift of the probe pulses when they are properly delayed around the rising or falling edge of the half-revival time of the ...
متن کاملSynchronization of femtosecond laser and electron pulses with subpicosecond precision
The temporal evolution of electron shadow images, formed by the projection of primary femtosecond electron pulses probe over a metal target and perturbed by the transient space-charge field near the target surface induced by the excitation of femtosecond optical pulses pump , is recorded in real time. By quantitatively analyzing the evolution of these shadow images as a function of pump-probe d...
