Biexcitons in Carbon Nanotubes
Fullerenes, Nanotubes and Carbon Nanostructures, 2005Abstract One‐dimensional confinement in carbon nanotubes leads to pronounced excitonic effects. With recent advances in ultrafast optical spectroscopy on isolated nanotubes, multi‐photon excitations such as biexcitons become accessible. Using an effective‐mass model of such excitations we predict that stable biexcitons will be found in all ...

physica status solidi (b), 2006
AbstractWe present two‐photon excitation luminescence experiments on carbon nanotubes which show the excitonic origin of the optical excitations. The two‐photon allowed exciton state, which has even parity under rotation about the U‐axis, is roughly 300 meV above the one‐photon active, odd‐parity state.

Properties of Carbon Nanotubes
2014Carbon nanotubes are certainly the most studied nanomaterials ever, considering the cumulated number of papers devoted to them since the 1990s (Fig. 1.1). Only graphene will possibly overcome nanotubes in this regard one day, specifically because of the boosting effect of the Nobel Prize dedicated to it in 2010.

Extreme oxygen sensitivity of electronic properties of carbon nanotubes
Science, 2000The electronic properties of single-walled carbon nanotubes are shown here to be extremely sensitive to the chemical environment. Exposure to air or oxygen dramatically influences the nanotubes' electrical resistance, thermoelectric power, and local ...

Hemotoxicity of carbon nanotubes
Advanced Drug Delivery Reviews, 2013Carbon nanotubes may enter into the bloodstream and interact with blood components indirectly via translocation following unintended exposure or directly after an intended administration for biomedical purposes. Once introduced into systemic circulation, nanotubes will encounter various proteins, biomolecules or cells which have specific roles in the ...

Tensile loading of ropes of single wall carbon nanotubes and their mechanical properties
Physical Review Letters, 2000The mechanical response of 15 single wall carbon nanotube (SWCNT) ropes under tensile load was measured. For 8 of these ropes strain data were obtained and they broke at strain values of 5.3% or lower.

Topics in Current Chemistry, 2017
Sorting of single-wall carbon nanotubes by their electronic and atomic structures in liquid phases is reviewed in this chapter. We first introduce the sorting problem, and then provide an overview of several sorting methodologies, following roughly the chronological order of their development over the past 15 years or so.

Noncovalent sidewall functionalization of single-walled carbon nanotubes for protein immobilization.
Journal of the American Chemical Society, 2001Single-walled carbon nanotubes (SWNTs) are molecular wires that exhibit interesting structural, mechanical, electrical, and electromechanical properties. 1-3 A SWNT is unique among solidstate materials in that every atom is on the surface.

Carbon Nanotubes for Microelectronics?
Small, 2005AbstractDespite all prophecies of its end, silicon‐based microelectronics still follows Moore's Law and continues to develop rapidly. However, the inherent physical limits will eventually be reached. Carbon nanotubes offer the potential for further miniaturization as long as it is possible to selectively deposit them with defined properties.
