- 論文の詳細を見る
Electronic transport properties of weakly and strongly coupled carbon nanotube quantum dots are investigated using one device. After transition from a weakly coupled dot to a strongly coupled dot, both height increases and broadening of Coulomb peaks are observed due to increasing tunneling rate. From the measurements of Coulomb diamonds, twofold degeneracy is observed for a weakly coupled dot, and twofold and fourfold degeneracy is observed for a strongly coupled dot. The excitation lines due to the confined levels disappear after the transition to strong coupling.
