| 摘 要： | 报道了单根碳纳米管的低温电输运测量结果,特别关注了由于碳纳米管在长度方向的尺寸较小时产生的库仑阻塞性质,碳纳米管的低温电输运出现了零偏置反常和库仑振荡。因此碳纳米管在小的尺寸和低温时不仅出现能量量子化而且可以出现电荷量子化-量子点的行为。

| Abstract: | This article reports on the low-temperature electron transport experimental results of individual carbon nanotube,which is focused on the Coulomb blockade for the length of carbon nanotube is reduced.At low temperatures,zero bias anomaly and Coulomb oscillation are observed on the individual carbon nanotube.Therefore,at low temperatures,small-sized carbon nanotube shows not only the energy quantization but also the charge quantization.The latter acts like the characteristics of quantum dot. |

| Keywords: | carbon nanotube coulomb blockade quantum dot |
