Gate-controlled generation of optical pulse trains using individual carbon nanotubes
M. Jiang, Y. Kumamoto, A. Ishii +3
We report on optical pulse-train generation from individual air-suspended carbon nanotubes under an application of square-wave gate voltages. Electrostatically-induced carrier accu…

Stark effect of excitons in individual air-suspended carbon nanotubes
M. Yoshida, Y. Kumamoto, A. Ishii +2
We investigate electric-field induced redshifts of photoluminescence from individual single-walled carbon nanotubes. The shifts scale quadratically with field, while measurements w…

Spontaneous exciton dissociation in carbon nanotubes
Y. Kumamoto, M. Yoshida, A. Ishii +3
Simultaneous photoluminescence and photocurrent measurements on individual single-walled carbon nanotubes reveal spontaneous dissociation of excitons into free electron-hole pairs.…
