Ballistic and resonant negative photocurrents in semiconducting carbon nanotubes
Christoph Karnetzky, Lukas Sponfeldner, Max Engl +1
Ultrafast photocurrent experiments are performed on semiconducting, single-walled carbon nanotubes under a resonant optical excitation of their subbands. The photogenerated exciton…
