Intersubband decay of 1-D exciton resonances in carbon nanotubes
Tobias Hertel, Vasili Perebeinos, Jared Crochet +3
We have studied intersubband decay of E22 excitons in semiconducting carbon nanotubes experimentally and theoretically. Photoluminescence excitation line widths of semiconducting n…
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…
Exciton Ionization, Franz-Keldysh and Stark Effects in Carbon Nanotubes
Vasili Perebeinos, Phaedon Avouris
We calculate the optical properties of carbon nanotubes in an external static electric field directed along the tube axis. We predict strong Franz-Keldysh oscillations in the first…
