Multiwall carbon nanotube SET transistor |

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). |
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). The size of the structure is one flux quantum in each direction, in agreement with theoretical expectations.
