Multiwall carbon nanotube SET transistor

The figure shows two example of a recent low-temperature transport experiments with multiwall nanotubes.
The figure shows two example of a recent low-temperature transport experiments with multiwall nanotubes. This amazing "face"-type images represent gray-scale maps of the nanotube electrical conductance, measured with respect to two variables: magnetic field (horizontal axis), applied parallel to the tube, and the bias voltage (vertical axis).

This amazing "face"-type images represent gray-scale maps of the nanotube electrical conductance, measured with respect to two variables: magnetic field (horizontal axis), applied parallel to the tube, and the bias voltage (vertical axis). The size of the structure is one flux quantum in each direction, in agreement with theoretical expectations.

  • The cylindrical superstructures are composed of silver nanoparticles with V-shaped amphiphilic arms. The short rod-like and spherical assemblies are made of gold nanoparticles with the same V-shaped amphiphilic arms.  The self-assembly occurs upon slow addition of water to solution of nanoparticles in organic solvent called tetrahydrofuran. The resulting mixture is then dialyzed against pure water in order to remove organic solvent and obtain a pure aqueous solution of the superstructures (they remain in water without any precipitation, just like micelles).
