We have fabricated single and coupled quantum dots in single-wall carbon nanotubes, and measured their electrical transport at low temperatures. The charging energy for single quantum dots seemed to depend on the gap between metallic contacts, and could be larger than room temperature for the smalle
Transport measurements on a bundle of single-walled carbon nanotubes have been made below 4.2 K as a function of side gate and source-drain bias voltage. The transport of an individual nanotube is described by the Coulomb blockade effect. The zero-dimensional quantum states of the nanotube become cl
The states of two electrons in a semiconducting nanotube dot are computed by exact diagonalisation of a 2-band effective mass Hamiltonian and compared to the states obtained from a molecular model. The molecular model is found to be accurate for the ground and excited states in a wide range of nanot
