“…In this context, the present result is more similar to the case of semiconductor quantum structures [5][6][7] and agrees with the theoretical predictions. 8,9 Since a SWCNT is an ideal quantum wire with a diameter of approximately 1 nm, the shifts in the transverse field strongly suggest the occurrence of the QCSE in the SWCNT.…”

“…[5][6][7] Since SWCNTs are ideal quantum wires, the QCSE in SWCNTs has been theoretically predicted. 8,9 However, the electricfield-induced optical changes in a SWCNT have never been investigated, because of the high conductance due to the contamination of metallic nanotubes. Recently, the fabrication of back-gated thin-film transistors ͑TFTs͒ has been reported and opened a way of applying spectroscopy to SWCNT as a function of gate voltage without a current flow.…”

The effect of an externally applied electric field in single-walled carbon nanotubes was studied using a thin-film transistor configuration. Under the electric field, the optical spectra displayed redshifts and broadening. These phenomena present evidence of the Stark effect in single-walled carbon nanotubes. The finding of the Stark effect suggests the potential use of carbon nanotubes in electro-optic devices for optical communication.

“…Theoretically, energy bands for commensurate DWCN's and/or MWCN's have been calculated and energy-level separation due to the intertube transfer [17,18,19,20] and result-ing reductions of the conductance have been reported [20,21]. For some incommensurate DWCN's, the density of states was calculated and a weak effect of the intertube transfer near the Fermi energy has been reported [22].…”

Electronic states and transport properties of double-wall carbon nanotubes without impurities are studied in a systematic manner. It is revealed that scattering in the bulk is negligible and the number of channels determines the average conductance. In the case of general incommensurate tubes, separation of degenerated energy levels due to intertube transfer is suppressed in the energy region higher than the Fermi energy but not in the energy region lower than that. Accordingly, in the former case, there are few effects of intertube transfer on the conductance, while in the latter case, separation of degenerated energy levels leads to large reduction of the conductance. It is also found that in some cases antiresonance with edge states in inner tubes causes an anomalous conductance quantization, G = e 2 /π , near the Fermi energy.

“…[6][7][8] The most distinguishable feature of multiwall nanotubes is that interwall interactions exist between neighboring shells. Previous theoretical calculations have shown that interwall interactions drastically alter the electronic and transport properties of hybrid nanotube structures, such as pseudogap opening in the ͑5,5͒/͑10,10͒ double-wall nanotube, [9][10][11] antiresonances in nanotubes containing fullerene molecules, 12 and diffusive transport in incommensurate multiwall tubes. 13 Recent experiments 14 have reported that multishell transport is more likely to occur in multiwall nanotubes, contrary to the belief that the transport would be governed by the outermost shell.…”
