Abstract

We studied the discretized electronic spectra of double-wall carbon nanotube (DWCNT) quantum dots (QDs) in the Coulomb-blockade regime. At low temperatures, the stability diagrams show a clear and regular eight-electron periodicity, which is due to the nonzero intershell couplings. Furthermore, the electronic charging energy, the energy level spacing, and the intershell coupling strengths of the measured DWCNT QDs were determined.
