Multi-wall carbon nanotubes as quantum dots [PDF]
Physical Review Letters, 2001 We have measured the differential conductance dI/dV of individual multi-wall carbon nanotubes (MWNT) of different lengths. A cross-over from wire-like (long tubes) to dot-like (short tubes) behavior is observed.

Double Quantum Dots in Carbon Nanotubes [PDF]
Physical Review B, 2010 We study the two-electron eigenspectrum of a carbon-nanotube double quantum dot with spin-orbit coupling. Exact calculation are combined with a simple model to provide an intuitive and accurate description of single-particle and interaction effects.

Quantum Dot Modified Multiwall Carbon Nanotubes [PDF]
The Journal of Physical Chemistry B, 2006 A novel strategy for the fabrication of multiwall carbon nanotube-nanocrystal heterostructures is shown. Different quantum dots (QDs) with narrow size distributions were covalently coupled to carbon nanotubes (CNTs) and silica-coated CNTs in a simple, uniform, and controllable manner. The structural and optical properties of CNT/QD heterostructures are
