چکیده
The electronic properties of single-walled carbon nanotubes (SWNTs) are altered by intertube coupling whenever bundles are formed. These effects are examined experimentally by applying Rayleigh scattering spectroscopy to probe the optical transitions of given individual SWNTs in their isolated and bundled forms. The transition energies of SWNTs are observed to undergo redshifts of tens of meVs upon bundling with other SWNTs. These intertube coupling effects can be understood as arising from the mutual dielectric screening of SWNTs in a bundle.

Rayleigh Scattering Spectroscopy
Single-wall carbon nanotubes can be probed optically by elastic light scattering. This effect forms the basis of a technique, termed Rayleigh scattering spectroscopy, for the study of individual nanotubes. Spectroscopic information on the electronic transitions of both semiconducting and metallic nanotubes is obtained by measuring the elastic scattering cross section as a function of photon ene...

In this talk, we describe recent experimental investigations of optical spectroscopy at the level of an individual nanotube. The principal experimental method has been Rayleigh scattering (elastic scattering) spectroscopy, an approach suitable for probing both semiconducting and metallic nanotubes. Recent measurements include a direct determination of the correlation between optical spectra and...
متن کاملProbing electronic transitions in individual carbon nanotubes by Rayleigh scattering.
Rayleigh scattering spectra were obtained from individual single-walled carbon nanotubes with the use of a laser-generated visible and near-infrared supercontinuum. This diagnostic method is noninvasive and general for nanoscale objects. The approach permits clear identification of excited states in arbitrary metallic and semiconducting nanotubes. We analyzed spectral lineshapes in relation to ...

We report a novel on-chip Rayleigh imaging technique using wide-field laser illumination to measure optical scattering from individual single-walled carbon nanotubes (SWNTs) on a solid substrate with high spatial and spectral resolution. This method in conjunction with calibrated AFM measurements accurately measures the resonance energies and diameters for a large number of SWNTs in parallel. W...
متن کاملDetermining the Chiral Index of Semiconducting Carbon Nanotubes Using Photoconductivity Resonances
We utilize photoconductivity spectroscopy to identify the unique chiral structure of individual carbon nanotubes (CNTs). Peaks in photoconductivity are measured throughout the visible and near-IR wavelength ranges. Photoconductivity peaks associated with individual CNTs are referenced against existing Rayleigh scattering measurements to uniquely identify chiral indices. We find close agreement ...
