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…

Giant circular dichroism in individual carbon nanotubes induced by extrinsic chirality
A. Yokoyama, M. Yoshida, A. Ishii +1
Circular dichroism is widely used for characterizing organic and biological materials, but measurements at a single molecule level are challenging because differences in absorption…

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.…
