我们研究了封闭金属纳米管量子点的离散电子能谱。在低温下，稳定性图显示出非常规则的四重模式，可以确定电子加成和激发能。测量的纳米管光谱与基于纳米管能带结构的理论预测非常一致。我们的结果允许完全识别纳米管量子点中的电子量子态。
We have studied the discrete electronic spectrum of closed metallic nanotube quantum dots. At low temperatures, the stability diagrams show a very regular four-fold pattern that allows for the determination of the electron addition and excitation energies. The measured nanotube spectra are in excellent agreement with theoretical predictions based on the nanotube band structure. Our results permit the complete identification of the electron quantum states in nanotube quantum dots.
