Universal non-resonant absorption in carbon nanotubes
Fabien Vialla, Ermin Malic, Benjamin Langlois +6
Photoluminescence excitation measurements in semi-conducting carbon nanotubes show a systematic non-resonant contribution between the well known excitonic resonances. Using a globa…
Unifying the low-temperature photoluminescence spectra of carbon nanotubes: the role of acoustic phonon confinement
Fabien Vialla, Yannick Chassagneux, Robson Ferreira +6
At low temperature the photoluminescence of single-wall carbon nanotubes show a large variety of spectral profiles ranging from ultra narrow lines in suspended nanotubes to broad a…
Hot electron cooling by acoustic phonons in graphene
A. C. Betz, F. Vialla, D. Brunel +8
We have investigated the energy loss of hot electrons in metallic graphene by means of GHz noise thermometry at liquid helium temperature. We observe the electronic temperature T /…
