ABSTRACT
A large current flowing process has been used at 1.5 K to modify transport properties of quantum dots in a bundle of single-walled carbon nanotubes. After the processes were applied to the samples a few times, Coulomb oscillations started to be observed that did not appear before the process. The number of Coulomb peaks decreased as the process was repeated. The experimental observations could be explained by the simple model that the nanotube bundle was composed of many single and multiquantum dots in parallel, and some of them were broken by the current flowing process. © 2003 American Institute of Physics.

    Modulation-doped InAs/GaAs quantum dots (QDs) show bright photoluminescence (PL) at 300 K, linear increase of PL intensity on excitation at 300 K and rather temperature insensitive PL intensity and carrier lifetime, in contrast to undoped QDs. Systematic analyses indicate that those advantageous...
