Beam-induced movement attenuation with single-wall carbon nanotubes

Single-wall Carbon Nanotubes with Ferromagnetic Electrodes

The electron transport in single-wall carbon nanotubes is one-dimensional and ballistic. Typically carbon nanotubes form tunneling contacts to electrodes and behave as quantum dots at low temperatures. We report on experiments on carbon nanotubes contacted with ferromagnetic metal. In these devices strong hysteretic magnetoresistance is observed at low temperatures. A possible interpretation of...

Ultralong single-wall carbon nanotubes.

Since the discovery of carbon nanotubes in 1991 by Iijima, there has been great interest in creating long, continuous nanotubes for applications where their properties coupled with extended lengths will enable new technology developments. For example, ultralong nanotubes can be spun into fibres that are more than an order of magnitude stronger than any current structural material, allowing revo...

Single-wall Carbon Nanotubes: Quantum Carbon Wires

Today’s business environment is causing utilities to examine methods to cut costs and to maximize revenues. Development of a comprehensive program for marketing and utilization* of coal combustion by-products (CCBPs) by a utility can generate additional revenue streams; reduce operating costs at plants; and defer capital costs of developing new waste disposal capacity. These factors can be opti...

Phonon-induced dephasing in single-wall carbon nanotubes

Mechanism of electrolyte-induced brightening in single-wall carbon nanotubes.

While addition of electrolyte to sodium dodecyl sulfate suspensions of single-wall carbon nanotubes has been demonstrated to result in significant brightening of the nanotube photoluminescence (PL), the brightening mechanism has remained unresolved. Here, we probe this mechanism using time-resolved PL decay measurements. We find that PL decay times increase by a factor of 2 on addition of CsCl ...
