We present experimental results on low-temperature transport of an individual single-wall carbon nanotube (SWNT) quantum dot. Four-electron shell structures were observed, due to the twofold subband degeneracy of the SWNT in addition to the twofold spin degeneracy. The excitation spectroscopy with a large source–drain voltage has made it possible to clearly observe the simple Zeeman splitting of single-particle states in a shell, and a textbook model of an interacting two-electron system has been demonstrated with directly distinguishable singlet and triplet states when the shell was half-filled.
