摘要：

We present experimental results on the electrical pulse-excited transport measurements of an individual single-wall carbon nanotube (SWNT) quantum dots. By applying a square pulse signal, the pulse-excited Coulomb peaks are observed in Coulomb oscillation measurements. In the SWNT quantum dot, the even-odd effect is confirmed by the alternate change of the Coulomb diamond size in the standard dc measurement. Magnetic fields perpendicular to the tube axis have revealed the simple Zeeman splitting of single particle states, this splitting is directly observed in the pulse-excited current in even-odd regime. We find the spin relaxation time at least longer than 1 mu s.
